@Ambrzyk You should really open a new thread. Seems not related to this issue, which was OFMKTO and already closed as won’t-fix.
When you do… please share the actual crash logs and/or dmp files.
Files that look like this, in your User/Logs folder…

(If you’ve looked closely and verify there aren’t any… well that in itself is interesting, but would seem to point to hardware failure / overheating. Windows itself seems ok after these crashes? Can you monitor your cpu/gpu temps using HWMonitor or FrameView or similar tool?)
