Unavailable With Party

Since the Season 1 Update on October 28th, my squad & I are all receiving the same message: "Unavailable With Party" and all game modes are locked out with a 🔓 icon on them. All 4 of us are on PS5, have crossplay enabled, have updated the game to the latest version, and we cannot seem to get it to work. Any one of us can leave the party & join any game mode singularly, but not as a party.

• Closing the game and restarting it does not work.
• Restarting the console does not work.
• Rebooting modem/router does not work.

We simply cannot play a match together & it's infuriating.
