can't even join a game/game just closes and can't rejoin.

I cannot get into a game. When i'm supposed to go into the loading screen my league just stops working. When i press "reconnect" the loading screen doesn't open and it says that league of legends has stopped working. I can get into a game after restarting my pc but only for few minutes because it stops working. I've lost 2 games due to this problem now and getting slightly triggered :) . Is this problem linked to: "We're aware of a problem causing players to disconnect from their games, and are investigating the problem." or is this a separate problem?

The game worked fine for me on 9th of june. On the 10th of june i came across this issue. I'm playing on EUNE but the same problem occured on EUW aswell. Please help i'm addicted to the game and i cannot play.

I have reinstalled the game and tried to repair the client. Someone also claimed that it has something to do with avast so i uninstalled it and disabled my windows firewall aswell. Nothing has worked so i guess riot has fucked up bigtime.
