If MARVEL Cosmic Invasion keeps crashing on your PC, start by noting exactly when it fails, then check the game’s Windows requirements, restart your PC and Steam, update Windows and relevant drivers, verify the game files, and temporarily close non-essential background software. These are general troubleshooting steps—not a guaranteed fix or proof of one universal cause. If the crash continues, send Dotemu the error and your PC details.
First, identify when the crash happens
Before changing settings, record the exact error message, if any, and what was happening when the game closed. A crash before a window appears may be different from one during loading or after a particular in-game action. Note whether it happens every time or intermittently, in solo play or multiplayer, and whether you can reproduce it with a specific stage or action. These clues help distinguish symptoms; they do not, by themselves, establish a cause.

Check your PC against the published Windows requirements
Steam lists the following requirements and performance targets for the Windows version of MARVEL Cosmic Invasion. They are published specifications, not a guarantee that every system meeting them will run without crashing.

Try these low-risk troubleshooting steps in order
- Restart the PC and Steam. Save any open work, restart Windows, then launch Steam and try the game again. Steam recommends a fresh restart as an initial check for launch problems.
- Install available Windows and hardware-driver updates. Check Windows Update and the appropriate driver-update channel for your graphics hardware. Steam recommends current Windows and drivers for general launch issues; this is not a confirmed game-specific fix.
- Verify the game files in Steam. In the Steam Library, right-click MARVEL Cosmic Invasion (or open its gear menu), choose Properties, open Installed Files, and select Verify integrity of game files. Wait for verification to finish before testing again. Steam notes that one or more files may fail verification normally when they are local configuration files that are not replaced; that message alone does not necessarily mean the repair failed.
- Temporarily close non-essential background software. Exit only applications that are safe to close, then retry the game. Steam advises checking for software conflicts, but the available game-specific information does not identify any particular overlay, security product, or other application as a known cause.
Make one change at a time and retest. That makes it easier to tell whether the symptom changed and gives support a clearer account of what you tried.
Do the official patch notes match your crash?

Those notes show that some specific bugs were addressed in particular patches.
