[Client] Black screen at champ select

Trying to get in an aram just now but before anything finishes loading, I hear what sounds like an immediate trade window opening and the screen just does not finish. Black save the border. Still had my three buttons at the bottom as well for friends, chat and notifications, and of course the window buttons at the top, of which I of course used the X since I was incapable of doing anything else within the game's window.
