Re: F1 23 error code PM65539 persists beyond all solutions - can't use multiplayer

Further update - I’ve also tried being invited to a game by a friend, updating to windows 11, moving my game back to the built in hard drive and disabling all firewall through settings, and again none of which made any difference. There’s an event on the game that I’d like to take part in tomorrow, so if you have any more ideas for me to try before then (short of a clean windows install) then let me know as soon as possible, thanks.
