I’ve got the same problem but on PS4. I can’t replace my realm with a different world or play a world as a realm. It’s definitely not to do with my world size as i’ve tried to play a new world on my realm but it doesn’t work. Might be something to do with the servers and the game going from 1.16 to 1.17? - I have no idea. Hopefully it gets fixed soon as it is quite frustrating spending money on a subscription service that doesn’t work as intended.
