It's a known issue with multiplayer on the PS5. I haven't looked into it in a couple of weeks because I've had other things I had to deal with and have kept me from gaming but I plan to look into it again soon.
It could definitely still be a me issue. It could be some sort of weird corruption with the save gamer something like that. I'm really not looking forward to trashing the entire safe game and starting the game over though.
PS5 actually. It's apparently a known issue and apparently it's isolated to the PS5 because it has something to do with the second players game not loading right when you're playing multiplayer couch co-op.
I had game save/hanging issues at first too, but figured out it was the cloud saving that was making the game hang. I turned off both the Larian cloud saves and Steam and then the game worked smoothly for me.
Hope it works! I do see with a brief search that there was apparently some kind of cross saving bug for PS5 and looking at headlines only Larian seems to have done something about it at least
I've played it and still don't understand the popularity. It's neat that you can do just about anything to just about anyone... You can kill major plot characters if you want, steal shit and get sent to jail... I dunno.
I just hope that next time I try to load a game, it doesn't hang the game. I'd like to continue playing it.
