I’m having some crash issues, but also wondering if this is the cause.
Discovered this today because I was noticing some strange issues with the framerate in a quick match lobby once a match is found and everyone joins. I was getting random crashes at the beginning of games.
I had nearly 40+ mods installed, but they were all disabled. Apparently deleting all of them fixed the framerate issues in the matchmaking lobby, and I haven’t had a crash yet. I guess this means disabled is not really disabled? 
If you have any mods installed and they are disabled, try deleting them as a test.
