Multiple shenanigans with client

Multiple crashes during champ select and even loading screen. also encountered where it crashed in a urf game I attempted to reconnect and it couldn't. So I completely exited everything LoL related and loaded the client. Now it would only be maybe a few minutes into the game at this point where I log in and poof.. I'm at the main screen and able to que into another game. While I was in the next urf game I heard every single ping and champion sound from the game I was supposed to be in whilst in the new one. spaghetti riot pls
