Quick Edit: Seemed to be an issue with the host's internet. My friend tried the internet at her Mom's and we loaded in just fine! Was nice to see our old world again and fry up some mutants in the dark lol

Making another post here among the rest for the PlayStation Co-op "Starting Client..." issue!

All possible details I can think of to reference for context:

My friend was hosting our world. We were on Day 106 and still hadn't rescued/killed our son.

She used a USB keyboard and entered the console command to make enemies only appear at night or in caves when we were about Day 65ish, because we were getting absolutely demolished by enemies any time we began cutting down trees. Everything worked fine.

She recently upgraded to a PS5 and she imported her save data over to the PS5 and we've been trying to get back to our save to finish it. I've had a PS5 since launch so I'm certain last time we played I was already on my PS5.

She has to be appearing online before I can sometimes find her listed on the server list. But sometimes even when she is appearing online, I still can't see it, even when I appear online.

On the times I have found her listed, I can join the little pre-game lobby and when she launches the game, she loads in fine, everything is loaded in and she can play normally, but I get stuck on "Starting Client..."

I don't dare try to make a new save because I don't want to overwrite my original save and lose all my items and my Days Survived.

Has anyone been able to figure out what is causing this issue?
