[CRASH] Bugspat every game

Hello,

Since the 6.23 patch I got a bug splat every time I join a game, when I tried to reconnect same problem.

After, joinning the game my game statrt to freeze/bug, lots of graphic bug then I crash bug splat or even blue screen.

I try to repair then redownload the patch but same problem. I though it was my graphic card so I updated it but same problem (Nvidia GT 630M).

Thanks for your help and your time.
