Finally someone with the same problem. I've been googling for hours and found nothing. It happened the first time yesterday, around the same time this thread was posted. I was going to join my friend's lobby like every other day but it just kept kicking me back to the main screen, no matter what we tried. We also tried using different saves, different playthroughs, even tried it on the PS5 too - no luck. There is no error message, it simply kicks me back to main screen after loading and on the host's screen it says something like "username left the lobby", and this happens when I'm the host as well. Today still the same issue. It has been working fine until yesterday. There were no changes made to our internet connections, we didn't touch our routers, nothing. We don't know what it is and it's driving us crazy because we can't continue our game. Hoping to find a solution here.
