I’m looking into this. Based on the logs the only lead I have is that something may have gone wrong with the installation, even if Steam’s integrity check passed.
Could you try reinstalling the game?
I know that’s annoying to hear, sorry about that, but we’ve got to rule out any weird installation problems before we can consider other possibilities.
Once you’ve reinstalled the game, if the problem still occurs: if you don’t use the skills you mentioned, are you able to play for long sessions without a crash? Does using these skills seem to lead to the crash, or is having them on your action bar sufficient?
We’ve been unable to reproduce this internally, so any information you can provide helps us figure this out.
