I'm currently having this issue aswell. Trying to upload my world on to my realm as it has an older version. Also would like to add upon failing to upload, any attempt to log in to the realm to play on the old map fails first time, there after i'm able to log in.
The upload begins then goes to initalizing after a delay im presented with "Failed an error occured"
Im on Windows 10
Bedrock edition
No addons/textures/behaviours
World size about 200mb
Would also like to note if I download the world from settings it also fails, however if I download from a cloud backup that was created no more than 30 minutes ago it will download fine.
