[Crash] Game crash, unable to reconnect

Hi, During normal game, there was a big bug. Game was frozen and i was unable to do anything. After restarting lol client there is a message that i should recconect because i have an active game. However, all attempst of reconnect end up with failure: "This game has crashed. Please ty to recconect to game". I am unable to recconect. It looks like i am still in game (this game last for 1:40 right now) and i am unable to do anything. Please try to fix it. Thanks.
