Loading screen stuck ps5 act 3

Hi, hope your well.

Me and my co-op player are stuck on loading screens. We're on PS5 in Act 3. The game won't let us join each others area. Warp or even waypoint, in or out of a party, doesn't matter how many ways or times we reset console/game. Restore licence etc, nothing works. So our progress/play is halted now untill it's resolved. We love the game and appreciate how complex these things are, thankyou for your time. Hope it can be fixed so we can go back on at some point. (Rob).

I am also experiencing this bug in the same area (Chimeral Wetlands) in couch co-op.
We are unable to progress. Base PS5 disc version. It has been an ongoing issue since the Dawn of the Hunt patch.
We took a break for a month and came back to try again, but lo and behold it was still the same issue.
