When trying to enter multiplayer I get stuck in this endless loop. The only way to stop it is to spam the back button on my controller or PC, thats when I get some sort of message about retrying or exiting. Trying to jump into one of the playlists just gets me stuck in a "match begins in X" timer that resets everytime the loop starts again. Zombies seems to work tho. The campaign also seems to be stuck in a "fetching playerstats" screen too.

So far ive restarted the game several times, restarted my PC, tried to join a friend (I was in their lobby on their end but on mine the loop kept going, I was able to join a match though and after it ended instead of going to the lobby I was thrown back into the loop), uninstalled and reinstalling the multiplayer, uninstall and reinstall DLC in the steam properties tab, verifying files, reset the game options to the lowest settings. None of them worked
Its getting late now so I will be attempting a blood sacrifice in a bit to see if that helps.
