Can't launch sessions (infinite loading and then crash)

Hi! I have a big problem with my project, I’m not able to start a session, I get an infinite loading screen and then after about 10 minutes the game crashes without even starting the session.

I don’t see any problems in the output log and the message log so I don’t really know what to do.

Hopefully I can do something about this because it really stopped everything going on in the project. (I even tried rolling back of many snapshots without avail, maybe something is corrupted in my project?)

+1 here. I’m having the same issue. Every 1 out of maybe 15 tries to launch, results in success. Silent error with no log.
