[CRASH] Client not loading into game.

When trying to load into a ranked game, as Tahm Kench support, my game crashed, the client worked fine, but whenever i tried to load into the game i was given and error and sent back to the client. After that game ended in a remake, i tried the same thing again. I got into a game as support, picked Tahm Kench, and the same exact thing happened. I then went to normal que, and picked Braum, i got into my game this time, except while in game my keyboard stopped working.
