[Crash] League of Legends Stuck at Authenticating

I was in champ select for my Ranked Game and im not sure if this was the reason for the crash but i changed the size of the client in the options during champ select. I was in champ select and I alt tabbed to check a image a friend sent me when i tabbed back showed game is in progress i reconnected and then I wasn't able to see any of the enemy champs and minions weren't moving i tried relaunching client to try to fix it but then when i logged in it just gets stuck on authenticating i tried logging out and logging on, still no good I wasn't able to find a solutions so currently I am repairing client to try to fix it.
