Downloading latest realm world backup is stuck on "Preparing download"

My friends and I have been playing on a Realm for a few months and the world has run its coarse. I would like to download it so that I can keep a copy of it, However when I go into the World Backups and click "Download Latest" it just gets stuck on a screen that says "Preparing download" I've tried a few times and stays like that until I cancel out of frustration. This point being 30 minutes to an hour almost.

 

This is different from the other issues I have seen on here, they have to do with "Preparing your world" after trying to upload a world to a realm.
