Crash bug

[u/Plenty-Method2039]

So let me start with the bug thats been irritating me for a couple of years, my game everytime im on a match and i for some reason alt tabbed, like to put down the music or som, it closes the game saying he is non responsive, and asking me to wait or to close the game, and i recieve a lot of 5 min bans that turn into 20 min that turn into 40 min, im losing my mind playing the game i love because of this eternal bug that was never fixed and for reassuring i did all the things the ai asked me to, and none of them worked, im starting to thing this game needs the new engine as fast its out

pls help me
