Team is heads down working on this as their number 1 priority to fix right now.
We think we have a workaround/fix that should get you out of this broken state:
- Stay in the lobby
- While in the lobby kill your internet connection to your PC
- Stay in the lobby and wait for the game to throw you back to the home screen
- Once on the home screen you should be good to reconnect your internet and queue for another game
