GPU crashed or D3D device removed error

Good afternoon,
I am new in Unreal and have a problem to run it properly. I am a little bit frustrating, because this problem I hadn’t in Unity Engine nor others.

The problem is, that I am not able to have open editor more than 5 minutes. Every time randomly appears popup with problem GPU crashed or D3D device removed error. It does not matter if I am creating new cube, move it, saving material. It’s randomly. In my scene are just default lights, player, floor and just one my created cube. I searched on forums, youtube, eg. and found some steps to do. I tryed it, but not resolve my problem.

  • Switched Direct X 12 to 11.
  • In Nvidia control panel I set power to prefer performance.
  • Add regedit params make I have now freeze computer longer time.
  • Deleted temp folders, etc. not solve.

My PC setup it WIndows 11 x64, Intel i7-12700H, 64 GB RAM, GeForce 3080 Ti.

So what to try next? Have somebody any idea? Thank you for you help.
