Regular applications should never crash your PC. It’s by design of modern operating systems. If application leads to PC crashes, than it’s most likely a bug in driver. Only drivers and OS pretty much can crash PC.
It’s possible that only Vermintide somehow manages to expose bug in a driver that leads to crash. We know that we have game crashes somewhere deeply in NVidia driver, but we never managed to reproduce it internally so we can capture full dump of the game and send over to NVidia. So I assume it’s most likely crashes in gpu driver.
Unfortunately it’s impossible to say what might be the issue without crash dumps or way to reproduce this issue internally.
I need a little bit more information from you to look into this issue - your GPU driver version and and OS build version.
