[CLIENT] Bug involving champ select and accepting a match

So I opened league like normal started rank queue and when it was time to hit accept (i was on my phone and the screen was on) the accept screen popped up i accepted. Once i was in the champ select it was stuck on "pick a champ" at 0 seconds and i couldn't see the enemy team and i knew it was taking a long time to load eventually it said you failed to ban a champ when the screen didn't pop up. After that i was annoyed and ended up restarting my queue but i didn't have the league client opened on screen and every time when it was time to accept the league client popped up at the last time so it resulted as an afk and this happened 5-6 times and now i have a 30 minute ban This happened right after some patches I am currently going through full repair on league i will update if that solves anything but i never had this problem.

Edit Full repair didn't solve it I'm on another 30 minute leaver buster ban Edit 2 After my second buster i managed to get into a game but the bugs are still very much present im pretty sure it has to do with lag because it would get stuck at zero then it would load all champ picks and bans at one shot it might be third party programs or the fact i have a potato pc but i'm not entirely sure Edit 3 (Next Day) the bug seems to have stopped and everything is working normally
