Ive had trouble for almost a week with my realm

Once before my realm world got corrupted,  i had trouble uploading a new world for a day or 2 then it worked fine

However this time , being un able to play on the realm due to the current world on there being corrupted ive tried so many times to upload a new backup, rest the world or upload a different world but it physically wont let me chnage the realm world at all.
I try about 10 times in different ways evey day and nothing is working
Ive checked all FAQs, aske din the discord and conxated mojang and still have had no help
