Could you specify, if you have any overclocks or amd’s storemi?
I have currently the same problem as well. I recently upgraded to Ryzen 2600, gtx 1080 ti. I have overclocked the cpu, gpu, ram and also use the amd’s storemi feature for disk management so it’s hard to identify the issue, although the pc doesn’t crash while stress testing with prime95 or aida64, but maybe the system still isn’t stable enough.
I checked the %appdata%/fatshark/vermintide 2 logs and discovered that it crashes because of memory access violation so I think that it might be ram related, if you have overclocked ram as well. I will try to play the game with ram default settings and report back, if that was the cause. I also searched google for this issue and saw several posts about disabling in-game voice so you can try that as well.
