Constant crashing when playing together with missus

Ever since the update last week, whenever me and my wife play together, we can get halfway through a map and she will be instantly on the login screen. And upon relogging in, and taking a portal into my map, she is instantly back in the login screen. Doesn't even have a load screen or anything. Just instantly disconnected. We play on the same internet connection. Have tried hardwire, wifi (both normal and 5g), hotspot on one. It doesn't matter. Turned all settings off. Sound and whatever was recommended as bugged at the moment.

Extremely frustrating. As we have never experienced this issue before, until last week's update. And the update within the last day or two, hasn't fixed the issue. We can not find a reason for it to trigger.
We are both playing on ps5. Both have fresh reinstalls. Both cleared cache. Both rebuilt database.

Can this please be fixed asap? Thank you
