Marvel Rivals just hit you with an Unreal Engine crash window — a wall of technical text and a 'Send and Close' button. This is an Unreal Engine 5 crash, usually related to shaders or GPU issues.
Fix it:
- Delete the shader cache: go to %localappdata%\MarvelRivals\Saved\ShaderCache (or similar path) and delete everything in there. The game will recompile shaders on next launch
- Update your GPU driver to the absolute latest version — UE5 games are very sensitive to driver versions
- If the crash mentions 'D3D Device Lost' or 'GPU Crashed': lower your graphics settings, especially Ray Tracing, Shadow Quality, and Effects. Drop render resolution to 100% if it's higher
- Increase Windows virtual memory: System Properties > Advanced > Performance Settings > Virtual Memory > set to at least 16GB
- Disable Hardware-Accelerated GPU Scheduling in Windows Settings > Display > Graphics > Change Default Graphics Settings
- Delete the game's config folder: %localappdata%\MarvelRivals\Saved\Config — the game will regenerate default settings
- Disable any overclock on your GPU — UE5 shader compilation pushes the GPU differently than most games
- Verify game files on Steam to replace any corrupted engine files
- If you keep crashing, try switching from DX12 to DX11 if the game supports it in settings
When to seek help
If this error keeps happening after trying the fixes above, it may point to a deeper hardware or system issue. Consider professional help if:
- The crash occurs across multiple games or applications
- You see the same error after a clean Windows install
- Your PC is less than a year old (could be a warranty issue)
- You smell burning or hear unusual sounds from your PC
