Game crashed, every time I launch the game it crashes instantly on rejoining. Locked out of game

Only thing I change in the settings was that "act like fullscreen" option (i dont remember the specific wording) - added it before a previous game. alt tabbed during the second game with this option on, crashed, and now the game crashes on launch. can't open cant change settings. was able to try and rejoin a few times but it would crash on the first frame of me rejoining. I abandoned and now and locked out of game

Launching the game with proton experimental rather than 9.0-4 allowed me to launch the game. Would be call if a value dev could get rid of the match making cooldown tho
