Unreal Engine is exiting due to D3D device being lost AGAIN AND AGAIN

I was having a really hard time with this error after upgrading from 4.23 to 4.24. I had never seen it before, but after the upgrade this error would crash the engine on my about every 10-15 minutes. More frustrating was the lack of information I found regarding it.

I did 3 things that I believe finally fixed the error.

  • I reverted my NVIDIA Game Ready Drivers back to the 2/27/20 driver. Every driver I tried post-March '20 was crashing.
  • I uninstalled Geforce Experience.
  • I disabled my Intel integrated graphics card, so only my GPU is running.

Hope this helps.
