After messing around with the files for a while, I got nothing, the only thing I found is that its an achievement error, something like "the given key was not present in the dictionary" is what its causing the crash, no idea if its been solved already in a hotfix or anything, no idea how to solve it either

If my memory serves me right, the devs of this game got inspired by Cataclysm: Dark Days Ahead.
