Cannot access Realms after leaving beta

After leaving the Minecraft Beta, I cannot access Realms on Xbox.

I get a generic "You cannot play on Realms because of how your Microsoft Account is set up" message, despite the settings being valid. It has been at least a week since I left the beta. I have attempted reinstalling Minecraft which has not resulted in any change.

I can access Realms on other platforms while signed into the same Microsoft account, such as Nintendo Switch, Android, and Windows 10. This affects both Xbox platforms I own, which are Xbox One S and Xbox Series S.

If there is any data I can provide, please let me know. Thank you.
