[CLIENT] Sneaky client crash after champion select

After champion select, task manager shows that client is running, but the window never actually opens. Can be solved by force quitting client, allowing you to press the "reconnect" button: but you don't even notice that there's an issue until it's already been a minute or two, since you have to force quit before that reconnect option shows up. By the time you fix the issue, game has already started and gets remade.

Has never happened to me before today, but today it happened twice in a row (the only two times I played).

I'm guessing this is also happening to others, since an allied Rengar was also AFK during the second game.
