I think I’m having this same issue, been happening for a couple weeks now.
I have a realm. I've had the realm for a while, years I think. I have two kids - we all play multi-player in the realm from a single Nintendo Switch device, again - we played multiplayer on the realm for years, from one single device.
After the 2/14/2025 update to minecraft, I have not been able to play multi-player in my realm. When I try to join as a player 2 the screen splits, it starts to load, and then it goes back to single player / full screen.
Other friends of mine that I have invited to the realm are able to join, no issues there. I am up-to-date my switch and my minecraft game Ver. 1.21.62 I can play multi-player on all other games, including minecraft but ONLY in regular worlds, not in my realm.
