[Client Bug] Black Screen When Trying to Queue

This just started happening to me an hour ago, or so. Whenever I try to queue for both Ranked and Normal draft pick, I can't even get to the screen that let's me choose my role.

When I click "Launch" on either of them, I get a completely black screen, with the lobby/queue music playing, and at the top, where I can exit out of it, it says "Arranging Team...", and the screen just stays like that. I've tried having it up there for upwards of 15 minutes, and it's still there. Even closing and re-opening my client didn't help.

I can access the client store and my own page, so I have a connection. It's just the queue screen in particular that's acting odd.

Is there anyone else that's experiencing this? Or is it just me?
