LolClient has stopped working (Champion Select crash)

Was first pick in a ranked 5v5 on summoner's rift, when the game randomly crashed in champion select after I changed my skin. After locking in my champ (I was playing Ryze, and clicked to change my skin to tribal ryze when the game instantly crashed) I was forced to close the program and I lost lp because of it and suffered the usual 5 minute time ban.
