Relog before nearly every game

My League was going fine before the latest patch but now I always have to close the loading screen and reconnect otherwise I can't get into the game. My champ select froze and I wanted to close the loading screen but now my client won't open anymore. So I have alot of problems getting into a game and I saw other people have the same problem too. Help? ^^ (First time posting something in the forum, sry if this was already a topic)
