Black screen crash on game start
After champ select has ended and the game is supposed to begin, instead of the loading screen all I get is a black screen. It never connects no matter how long I wait. Clicking anywhere on the black screen causes a crash dialogue to pop up. Attempting to reconnect results in the same black screen. Restarting the client attempts to auto connect to the game and also just ends in the same black screen. I have to fully reboot my machine in order to connect.
This happens with both Ranked matchmaking and Practice Tool games.
