[CLIENT] Champ Select Not Appearing

Started a solo queue for an Ai game on twisted treeline. Found a match and my client space emptied after accepting the game. By empty I mean it went completely black with no options for clicking aside from closing out the client. I figured I'd wait and see what happens. After about a minute it kicked me back to the home page of the client and said I didn't pick a champion and now I'm on a five minute wait so I figured I'd throw this here while I wait. I'm glad I wasn't in a ranked queue because I would've lost LP.

EDIT: I closed my client and relogged afterwards and didn't have the issue on the next attempt.
