Game froze my entire pc

[Aglarele]

Download the game from the Steam farmfest screen, and it started automatically.
Game opened, I heard some music but couldn't click anything. (Not even Settings or Quit)

My entire pc froze, even alt f4 didn't work and couldn't click on the game in task manager to kill it. (It used 95% of my GPU, but only 50% of my CPU.) Had to shut it down to get my pc to work again.

At first I assumed my pc was just too old as I only have an Nvidea 1080, but it seems I even meet the recommended requirements.

Not sure what went wrong, but perhaps you don't support 4k screens?
