Constant crashes during the game (and game lags after a few games)

[kraevk37]

During the match, I was constantly thrown out into the menu after about every minute, and after that I decided to completely restart steam with the game, as a result of which I was banned because they say I went out myself. id 40791077

And I'll also add that the game's performance drops after a while and it starts to lags every 5-10 seconds.
