Can't play with friends and matchmaking disabled for all modes.

Everytime I try to play anything multiplayer it never works. Quick Match and ranked I can not queue for since it says matchmaking disabled. When I try to play with a friend it says cross-platform Error: C04T00R27X-01 4D504D610306 which if googled has 1 post on it and the steps didnt work. I also found 2 other people talking about this issue with matchmaking disabled, but no solutions. So I am asking you all here if you have ever seen this or had a friend see it and fixed it somehow because I can not play the game. I have tried restarting my pc, reinstalling the game, verifying files. I am on Steam btw.
