Game keeps crashing

FAF keeps crashing while playing campaign co-op games. It will usually happen after an extended period (50-60 minutes) at which point the game will freeze, although the sound continues and I can click on units.

I've attached a few logs, with different errors each time.

The crashes have occurred on multiple co-op maps; the original final Aeon mission, Black Day, Dawn and Mind Games.

I turned off Steelseries GG and my first extended game had no crashes... wow. I'll try again a few times. Thanks.
