Loaded into a game seven minutes late, and now my client is stuck like this

After 8.16 dropped, I played a bot game to get a small idea about what damage I can expect given that offensive runes were nerfed. The game launches, and loading is slow. Really slow. But I'm at 100%, so I should be fine right? Wrong, I load into the game and seven minutes have passed. Good thing it was a bot game, or else I'd feel really bad.

So I decided to play a game of Draft pick, thinking the above incident was just an anomaly. Nope, I didn't even load into this game. So I went on the practice tool to try and see if it's working. Now it won't even leave champ select. The client has been like this for 10-15 minutes now
