The same issue here since 3-4 days. Starting at 09th January we are not anymore able to play together as his PS4 freezes after max. 3 minutes after I'm connecting from my XB Series X to his world on PS4. I believe this is a PSN/Crossplay issue. If I open a new world on my XB he can join me without any problems and my XB will not freeze and everything seems to work correct. Connecting my XB to his PS4 doesn't anymore work, and his wolrd freezes after short time. PLEASE check this with the network gusy, what is wrong in the network infastructure on your site (or the PSN), which can cause this issue.
This must be a PS4 Crossplay issue, as there are many reports of this error since 3-4 days in the internet (Reddit and others).
@NyarOblivion
I don't think your issue is the same as this one, as we can connect and play for a short time until the host PS4 freezes. The connetion issues you have is a different thing, but may be the same source of the problem, if it had worked about 3 days ago. The above message come on the clients, if the host PS4 world freezes.
