Infinite loading screen party play ps5

The issue was intermittent and tolerable through first play through, happened at typical spots, chimeras wetlands etc. there are four of us playing, we are in cruel now and we have actually just stopped playing as a group because it became impossible. Without fail one out of three of us would get stuck in an infinite loading screen. We would show up to the other players and can hear them doing actions but never fully load in. All of us really like the game and we would restart, try different party leaders, try to wait until someone was fully loaded in before next one joined and nothing works. When we are stuck we either just have to force shut off the game and reload or open up split screen to get the character out of the screen. Two of the members are on the same ip and never have issues playing together, and the other two are in the same city and never have issues playing together, all of us are on the east coast and live a couple states away. I have seen this issue in multiple places but no responses from GGG. It is a shame because we have a lot of fun playing together but can’t beat the loading screen boss.
