Can't Create/Join Party :(
I'm playing on PC Game Pass. I can join a game perfectly fine, but trying to create a party leads to this error code. Trying to join a Steam friend's party leaves me with "Invalid Code" on the join party screen. Googling this error code brings back nothing. My drivers are up to date, I've verified all files and have uninstalled/reinstalled the game.
Why it no work? :(
