When Honkai: Star Rail will not launch, crashes, or shows a black screen, first identify where the failure happens: at startup, during gameplay, or while connecting at the train loading screen. Then use the matching official checks—verify game files and check drivers and device requirements for crashes; troubleshoot the connection for loading problems; and follow the specific guidance for any error code. A black screen alone does not identify one universal cause or fix.
First, identify when and how the game fails
Before changing settings, note what you see and when it happens. A game that closes unexpectedly calls for different checks from one that stays at the train loading screen.
- It will not launch or crashes/freezes: note whether the launcher opens, whether the game reaches the login screen, and whether it closes during startup or play.
- It shows a black screen: note whether the game is still running or responding, and whether an error code appears. A black screen is a symptom, not a diagnosis; HoYoverse’s FAQ result mentions that devices below minimum requirements may have startup problems or black screens, but that does not establish the cause in an individual case (HoYoLAB FAQ).
- It gets stuck at the train loading screen: treat this first as a possible connection or loading problem, especially if the game has not closed.
Record your platform, device model and specifications, operating-system version, and any error code. These details help distinguish a file, driver, device, network, or code-specific issue.
If Honkai: Star Rail crashes or freezes
HoYoverse’s crash and freezing guidance, updated September 30, 2025, starts with three checks: re-verify downloaded resources, update the graphics driver, and check that the device meets minimum requirements (HoYoverse Help Center: What Should I Do If My Game Keeps Crashing or Freezing?). These are general checks, not a guaranteed fix for every crash or black screen.

- Update the graphics driver: install the current driver for your graphics hardware. HoYoverse advises a clean installation, or completely removing the old driver before installing the new one.
- Check device requirements: compare your device with the current minimum requirements for your platform. Requirements may change as the client is updated; consult HoYoverse’s current official support information rather than relying on a remembered specification.
If it is stuck on the train loading screen
A loading stall can be connectivity-related even when the game has not crashed. HoYoverse’s train-loading guidance, updated September 25, 2025, recommends these checks (HoYoverse Help Center: Stuck on the Train Loading Screen):
- Restart your device and router.
- Check that your connection is working, then try a different network—for example, switch between Wi-Fi and mobile data.
- Temporarily disable a VPN or proxy, and check whether third-party software might be interfering with the connection.
- Set DNS to automatic.
If the problem continues after these checks, HoYoverse lists reinstalling the game as a later step. For download or update trouble specifically, HoYoverse recommends a stable connection, preferably a direct cable connection, or an alternative Wi-Fi connection (HoYoverse Help Center: Download/Update Issue Troubleshooting). A wired connection is a connectivity test for that context, not a general fix for graphics crashes or black screens.

If an error code appears, follow its matching instructions
Do not apply every repair at random. HoYoverse’s error-code guide, updated November 12, 2025, maps specific codes to file, network, antivirus, memory, process, or system conditions. Use the full official guide for the code and platform shown (HoYoverse Help Center: Error Code Guide).
- 2002-0-0: HoYoverse gives different guidance depending on hardware. CPU clock or overclock changes apply only to certain Intel 13th- or 14th-generation systems or equivalent overclocked systems; other users are directed to a HoYoverse repair utility. Do not change BIOS or CPU settings unless your hardware and code match the official instructions.
- 2000_0: on PC, the guide recommends verifying file integrity and trying another network; it describes registry removal only as a last step. On Android or iOS, verify files and reinstall if the issue continues.
- 4214: identified as a network connection issue; if you are using Wi-Fi, test mobile data.
- 8002 and the related codes listed in the guide: identified with corrupted files; HoYoverse recommends a complete uninstall and reinstall.
- Listed missing-driver codes: antivirus interference may be involved; the guide describes restoring files with launcher repair and reinstalling if needed.
- 1, 107, 126: use launcher repair or reinstall for missing local files.
- 1, 4, 5: HoYoverse identifies antivirus interference and lists named game files to add to the antivirus exception list. Follow the official code-specific directions.
- 1, 107, 0: the guide identifies a possible CPU compatibility issue on some 13th- or 14th-generation Intel systems and lists BIOS options. Treat this as advanced, hardware-specific guidance.
- 1, 5, 8: restart to free memory. 1, 5, 1238 or 3, 0, 0: close multiple game processes. 1, 4, 1084: exit Safe Mode. 5, 85001, 3500 or 5, 4, x: launch from the main operating system rather than a sandbox or virtual machine.
What to send HoYoverse if the problem persists
Useful diagnostics make it easier to investigate a repeatable crash or loading failure. For crashes and freezes, HoYoverse asks players to provide their UID, device model and specifications, screenshots or video, logs or dump files, and the exact crash time. On Windows, the listed diagnostic files include Player.log, Player-prev.log, .dmp files, and output_log.txt (HoYoverse Help Center: crash and freezing guidance).
HoYoverse warns: “Please retrieve the output_log.txt file while the issue is occurring, as the log resets after restarting.” Capture it before restarting the game. For a train-loading issue, include the platform and device details, CPU/GPU/RAM and operating system where applicable, region or country, ISP, connection type, and the requested network diagnostic screenshot or video. The loading-screen guidance asks for these details when contacting support (HoYoverse Help Center: train-loading guidance).
