After patch 5.4 my LoL client has been broken...

Basically as I go to join a game it will launch the game, crash then put me back to the client screen with the "click to reconnect" button, I have to do this several times before it lets me into a game, sometimes I even have to re log multiple times. I also cannot spectate games any more, if I try to, it lasts for 15 seconds then crashes. Anyone have any solutions?
