all but one of the hangs is in a dll called tier0_s64.dll which is managed by steam. The last one was in a steam api call but from my perspective it doesn’t look like it’s deadlock in that case, just really slow (15s update, which we cutoff as a deadlock).
Sadly we can’t investigate further than this. Try update your steam client. In the next patch we plan to improve deadlock reporting to find info from our exe if possible. But it’s not 100% we will get any more info with that update.
We also have better tools to debug hangs in the gameplay code with the same update or before that. Since the last hang indicated that it could be something else.
