I also have this issue on Bazzite running RTX 5080 in Kingdom Come Deliverance 2.

I have a save file that always instantly freezes when I load it. It only freezes if Global Illumination is set to Ultra or Experimental. If it's High or lower, it doesn't freeze at all.

@muff11n Can you try downloading my save file and loading it with all settings to Ultra and also with Global Illumination set to Low?
