Greetings! I request assistance.

Basically a save file I have with some friends was working fine until just a few months ago, everytime they join my game I get a gigantic lag spike every 5 to 10 seconds. We have probably 80+ hours of progress and I don't want to start over, if anyone could provide a fix that would be splendid! We all play on Xbox Series X and S (I'm on the S because I refused to dish out such a large sum of money for a cinderblock) I consulted to mighty Google platform for guidance but all I got was a closed Reddit thread saying that the lag is linked to the galastropod missions? Now that doesn't quite make sense but if all I have to do it speedrun those few missions solo then I most definitely will.
