Hi misnor,
I'm sorry you're getting a crash - unfortunately I think this is a bug related to UE4 itself (the game engine I used to make katabasis).
I've looked up the error message and it looks like a lot of other games that use UE4 have had reports of this too (ARK, Squad etc.).
Some potential fixes I've found:
- Rolling back your driver version (lots of people recommend this)
- Setting "Power Management" in Nvidia Control Centre to "Prefer Maximum Performance"
Let me know how you get on when you have the time!
