Accepting a Friendly match as casual game starts sends the game into a weird state

Title:

Summary:
After getting sent a friendly match invite, I got matched up for a casual match and the game went to neither match and instead was a black screen. Upon disconnecting and getting back to the main menu the screen was still black.

Steps to reproduce:

  1. Queue for casual (was queued for both ranked and casual)
  2. receive a friendly match request
  3. get matched into a casual match
  4. accept the friendly request quickly afterword (should note that it was coincidentally the same person)

Expected Results:
Either abort the casual match and go to the friendly match or block ability to accept the request for a friendly match

Actual Results:
Failed to get enter the match, but could choose to disconnect. Disconnecting sent me to a strange main menu.
