I also have this problem, I have been disabling mods on and off trying to figure out witch one it would be. But I also think that this is a problem in the base game. Also there seems to be a pattern when guns are being fired. Almost 90% of the cases the game crashes with raids because I obviously have to fire a gun lol.
Also this is the exception I have, although I think the exception isn't very relevant. It keeps changing.
EDIT
Apparently it has something to do with this bug in unity: https://issuetracker.unity3d.com/issues/linux-player-standalone-x86-64-builds-with-resolution-window-enabled-crash-in-funlockfile.
The game works fine if you use 32bit on linux, however slightly slower tho :/.
