Does this only happen when you are partied with a steam friend? Because that's the commonality I have found with my crashes. Once per game because the crash causes you to drop the party for the rest of the match.
The first I've heard this issue reported was June 2024, and it is STILL AN ISSUE. Can we please get an acknowledgement from Valve? I disconnect every single game I play partied with many of my steam friends and it's always at the WORST times during a match. Please fix this.
This happens to me as well. Usually during the early laning phase I will crash once per game only if I'm partied with a steam friend. Once the crash happens, it kicks me out of the party so I'm fine the rest of the match, but I will have to rejoin party to queue up again.
As the title says, every single game I play while partied with someone on my steam friends list will result in my game crashing exactly once per match. I can go weeks with no crashes, then one night play with a friend at it will crash every single game. Took awhile for me to catch on to this...
