possible corrupted files x.x

I was searching for some information here and i saw some posts 7 months ago about possible corrupted files very often after entering a ranked game, which is really awful cause because you have to wait around 5-10 minutes to re-enter the game, this bug already happened me 3 times in patch 5.17 and already twice in patch 5.18, and it really sucks because now im getting punished for "being afk" at games, please help
