UE5 Crash - Valley of the Ancient map

My walley demo crashes on direct3d lost error each time right after the scene is supposed to appear in UE editor.
My specs:

  • 3950x, RTX 3090, 128g RAM
  • newest drivers, all windows updates, sufficient SSD space

Anyone any tips? Moved demo to different drive as the error was mentioning D:/ drive but i had on C: and S:. Didn’t help unfortunately.
