My Realm Is not Working

When I try to upload my world to my realm, it gets stuck on "verifying world" for a while before giving me an error message "world could not be uploaded (-1)". I do not know what error (-1) means as this has never happened to me but I was trying to add another datapack to my realm, which my friends and I have over 500 hours of playtime on each. I have tried uploading the world to all 3 world options, but it gets stuck on the verification tab every time. I have tried uploading a different world to the realm, then uploading my world, but that has not worked either and now I am unable to access my realm backups. PLEASE help I do not want to lose this world, it means a lot to me and my friends. The amount of money I have spent just to keep this realm up should justify my desperation that this problem please be fixed.
