Anyone else getting permanently disconnected this patch (connection issues)?

I started up a new run this patch and things were going great, until it suddenly disconnected me, taking me back to the main menu with the "Connection Issue" written across the screen. Sure, it happens, I'm used to it. But now the second I click to resume my run I'm immediately booted out again because of those same "connection issues". It's also telling me I'm at 9 wins when I know I'm at 4 wins.

What's worse, I can't even concede because that requires me to be in the run. I've already restarted both the client and the game itself, but still the same results. I don't even care about the run (it was unranked), I just wanna play the new patch. Help?
