(Steam) MCC Halo 2 Anniversary crashing to menu

A friend and I were just playing the mission Oracle on MCC Halo 2 Anniversary and on two cutscenes the game will crash to main menu and wipe all progres forcing us to do the entire mission over. I’ve seen threads about this from over a year ago and it apparently is STILL an issue. Can someone from somewhere mention this at all? Forum admins? 343 support? Someone? This bug needs to get fixed, its insane that I cant play co-op on a game remembered and loved for the co-op experience.

This is listed as a known issue on the Halo Support page. Best submit a ticket - the more reports the higher the likely priority for a fix
