Game crashing without error after joining server

Hi,

My game was running fine previously for the last couple of months. The Anti-cheat update came and it was still running fine. However, since the last 2 days the game crashes on desktop after a couple of seconds of joining a new server. I tried to repair the game, uninstalling the AC(this works but the game randomly disconnects from the EA server). Reinstalling the AC and repairing again. The issue does not seem to be hardware related as, singleplayer seems to work fine. 

Any help would be appreciated. Thanks.
