From Nintendo AU:  (this has worked for us) 

If the game is loading for other users on the console then it indicates that the game's save data has become too large. Minecraft downloads/caches all visited worlds to the console in the form of the game's save data and it can become multiple gigabytes in size and can prevent the game from loading if this occurs.

Deleting the game save data should fix this problem. For Minecraft, this will not effect your purchases, progress or in-game items as these are saved to your Microsoft account in the game. At worst, doing so may prompt you to sign into your Microsoft account again when you next launch the game:

*From the HOME Menu, select System Settings.
*Scroll down and select Data Management, then Delete Save Data.
*Select the game title for which you want to delete the save data.
*Select the User for which you want to delete the save data. To confirm, select Delete Save Data.

thanks! 🙂

Sorry I am a novice with this - What were or are the work arounds?
