My game crashes after about 10 minutes with this error: "Fatal error: [File:Unknown] [Line: 187] - Unreal Engine is exiting due to D3D device being lost (Error: 0x887A0006 'HUNG')." My graphics drivers and operating system are fully updated. What troubleshooting steps can help identify and fix the problem?

This usually means the graphics driver reset because the GPU stopped responding. It can be caused by more than outdated drivers, including overheating, unstable overclocks or undervolts, excessive VRAM use, DirectX problems, an engine bug, or failing hardware. Check your GPU temperature and VRAM usage while playing, and return the GPU to stock settings if it has been overclocked.
If the game supports it, switch from DirectX 12 to DirectX 11 and test again. Also disable any GPU overclock or undervolt, verify the game files, and watch for temperature or memory spikes. Since several different issues can produce this error, testing these one at a time should help narrow down the cause.
Are there any specific fixes I should try first?
