AFK LEAVE BUSTER when leauge is the reason.

Hi i have never posted on here before, In patch 9.2 i keep having an glitch/bug where during the loading screen my computer would go completely black and an error message sound would appear. Nothing i do will make the screen revert back to normal except restarting the computer. This has caused me to get AFK leaver bustered twice for no reason. Riot if you are listening this is completely unfair . I did not get a chance to even load in the game because of this stupid bug and i am not going to waste another day with 20 minute wait timers because of this stupid bug.
