Windows Errors? Fix Them Before They Spread
Repair common Windows errors and clear accumulated junk for a smoother, more stable PC - no reinstall needed.Free scan · no reinstallCrashes, No Sound, or Screen Glitches?
Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minute“Cyberpunk 2077 has flatlined” is a generic REDengine crash message, not a single diagnosed error. The fix depends on where startup fails: the store launcher, REDlauncher, the game executable, a modified installation, Windows, graphics drivers, or a runtime component. Work through the steps below in order, starting with reversible checks. If you use mods, trainers, or injected DLLs, treat those as the first suspect and back up your saves before removing files.
CD PROJEKT RED’s PC support hub currently lists Patch 2.31 as the latest version shown on that page, so update the game before testing version-specific fixes: CD PROJEKT RED PC support.
What the “has flatlined” message means
The crash reporter appears when Cyberpunk 2077 or REDlauncher terminates unexpectedly. The popup alone does not identify the cause. A crash before the game window appears commonly points to the launcher, permissions, overlays, drivers, Windows, missing Visual C++ components, or damaged files. If the problem began after adding mods, trainers, or custom DLLs, treat modified content as the leading branch first.
For escalation, CD PROJEKT RED may use the report’s stacktrace.txt, but it is support evidence rather than a guaranteed diagnosis. The support workflow also asks whether the game starts directly from its installation folder and whether mods or trainers were used: launch-crash support instructions.

#1 Best Overall
Check compatibility before changing the installation
- Use a 64-bit, currently supported Windows build.
- Compare your CPU, GPU, memory, storage, and DirectX capability with the current requirements on CD PROJEKT RED’s system-requirements page.
- Minimum requirements do not guarantee stability with ray tracing, path tracing, high-resolution texture replacements, or large mod packs.
Try these low-risk fixes first
- Restart Windows, then start the game from Steam, GOG Galaxy, or Epic Games Store rather than an old desktop shortcut.
- Exit overlays and background utilities: Discord, NVIDIA App or GeForce Experience overlay, AMD overlay features, Xbox Game Bar, GOG or Ubisoft overlays, MSI Afterburner/RivaTuner, RGB-control software, recording tools, and hardware monitors.
- Temporarily pause third-party antivirus or anti-malware protection only for a controlled test. Check its quarantine/history first, restore any wrongly quarantined file, and turn protection back on immediately.
- Return CPU and GPU overclocks, undervolts, custom memory profiles, and other tuning to stock settings if the crash followed a BIOS or hardware change.
- Remove every custom launch option or command-line parameter.
CD PROJEKT RED specifically recommends disabling overlays, unnecessary applications, monitoring tools, and security software while diagnosing crashes, and returning altered clock rates to stock: official crash troubleshooting.
Disable mods, trainers, and injected files
For a modded installation, do not assume that uninstalling a mod manager removed everything. Frameworks such as RED4ext, redscript, Cyber Engine Tweaks, ArchiveXL, TweakXL, REDmod, manually copied DLLs, and trainers can leave files in the game directory. CD PROJEKT RED does not support individual mods and recommends a clean installation when modified content causes problems: modified-content guidance.
- Disable all mods in the mod manager.
- Remove trainers and third-party DLL injectors.
- Clear custom launch parameters.
- Test the unmodified game.
- Only after it launches, reinstall mods in small groups, beginning with required frameworks and checking compatibility with your installed game version.
Community troubleshooting guides also recommend disabling everything, verifying files, and re-enabling mods in batches: CDPR Modding Documentation and REDmodding. This is community practice, not a guarantee. Mod effects can persist in saves, so back up %userprofile%Saved GamesCD Projekt RedCyberpunk 2077 before extensive removal.

Run the store launcher as administrator
- Exit the game and completely close Steam, GOG Galaxy, or Epic Games Store.
- Right-click the relevant launcher and choose Run as administrator.
- Launch Cyberpunk 2077 normally.
Use elevation as a diagnostic step rather than permanently setting every executable to administrator; it will not repair corrupted files, drivers, or mods. See CD PROJEKT RED’s launch procedure: Game is not launching.
Verify or repair the game files
Use the menu for your store:
| Store | Current path |
|---|---|
| Steam | Library → right-click Cyberpunk 2077 → Properties → Installed Files → Verify integrity of game files |
| GOG Galaxy | Owned games → Cyberpunk 2077 → Customize → Manage installation → Verify/Repair |
| Epic Games Store | Library → three dots beside the game → Manage → Verify |
These procedures can replace missing or damaged official files. They may not remove third-party files, injected DLLs, old mod frameworks, or incompatible configuration data. A successful verification therefore does not prove that a modded installation is clean. Instructions: CD PROJEKT RED file verification guide.
Stop repeating verification if it reports no errors, the crash began after modding, the direct executable also fails, or the problem started immediately after a driver update. Move to the relevant branch below.

Update or clean-install the graphics driver
- Identify whether your GPU is NVIDIA, AMD, or Intel.
- Download the driver for your exact GPU and Windows version from the manufacturer’s official site.
- Use the vendor cleanup method or CD PROJEKT RED’s recommended procedure.
- Reboot when prompted and install with the clean-install option where available.
- Test Cyberpunk 2077 before reinstalling overlays, tuning tools, or recording utilities.
- NVIDIA: CD PROJEKT RED lists Display Driver Uninstaller (DDU), followed by a clean installation of the downloaded driver.
- AMD: use AMD Cleanup Utility, then install the current driver.
- Intel: use DDU, then clean-install the current driver.
DDU is a powerful tool; download it and the driver only from reputable official sources and select the correct hardware. If the crash began immediately after a driver update, CD PROJEKT RED says trying the previous driver can be appropriate. Details: CD PROJEKT RED crash guidance.
Reinstall Microsoft Visual C++ Redistributables
Download the official Microsoft Visual C++ Redistributable packages and reinstall both x86 and x64 versions, running the installers as administrator as CD PROJEKT RED recommends: launch troubleshooting. A 64-bit package does not replace every 32-bit dependency. Do not download individual DLLs from “DLL fixer” sites. An MSVCP140_1.dll error is a related runtime-dependency symptom, not a reason to use unofficial replacement files.

- Launch the game again so the launcher can be recreated.
This removes launcher files, not your save games. Official instructions: REDlauncher troubleshooting.
Interpret the result
- If REDlauncher never opens, keep investigating the launcher, permissions, and its files.
- If REDlauncher opens but the game flatlines after Play, focus on mods, files, drivers, overlays, dependencies, and Windows.
Update Windows and check DirectX compatibility
Press Windows key + R, enter winver, and press Enter. CD PROJEKT RED documents launch crashes on older Windows 10 builds because the game uses a newer DirectX 12 version. Its dedicated page identifies builds below Windows 10 version 2004, while an older general page still mentions 1909. Do not choose between those historical thresholds: update to a currently supported Windows build and consult the current requirements page. See the dedicated DirectX/Windows notice and the current PC support hub.
Test the game executable directly
Open the installation folder and run:
...Cyberpunk 2077binx64Cyberpunk2077.exeThis is a diagnostic test, not necessarily a permanent workaround.

When to perform a clean installation
Use CD PROJEKT RED’s official clean-install procedure—not an improvised deletion list—when mods or trainers were used, files were manually copied, the game moved between drives or launchers, verification repeatedly succeeds without fixing the crash, scripts are missing or corrupt, or a normal reinstall left the problem unchanged. Back up saves first; game installation files and saves are separate. The modified-content article explains the supported approach: clean-install guidance. A clean install removes leftovers but cannot correct unsupported hardware, unstable overclocks, defective drivers, or Windows problems.
Collect logs and contact CD PROJEKT RED
If the decision branches do not resolve the crash, submit a support ticket with reproducible details rather than deleting system files or downloading replacement DLLs.
- Open Windows Explorer and paste
%localappdata%REDEngineReportQueue. - Open the folder with the newest modified date and attach
stacktrace.txt. - Press Windows key + R, enter
DxDiag, press Enter, choose Save All Information…, and attach the report. - Include your store (Steam, GOG, or Epic), displayed game patch, Phantom Liberty status, Windows version, GPU driver version, mod/trainer history, whether direct executable launch works, and what you already tested.
DxDiag contains detailed system information. Review attachments for personal data before posting them publicly. Support instructions and log paths: CD PROJEKT RED contact form. Your saves are normally at %userprofile%Saved GamesCD Projekt RedCyberpunk 2077; the save-location reference is here.
Advanced, hardware-specific checks
Older community reports describe failures involving dedicated audio interfaces, ASIO drivers, Nahimic services, monitor connections, and other peripherals. These are anecdotal possibilities, not universal fixes. If the crash began after a hardware change, test with motherboard audio, temporarily disable Nahimic-like enhancement services, disconnect nonessential USB audio devices, or try another display connection. Examples of community reports include GOG and CD PROJEKT RED forums.
