Still have this problem.

Suggested fix to uninstall, redownload/install them delete saved Microsoft account data.

As above. Works first time but then soon breaks again fails to load any skins not allow access to marketplace.

Also noticed glitches when placing blocks in water whilst on realms server.

Behaviour an Resource packs folders are empty in my world save
upload limited to 35mb/s (am on 500 fibre)
Minecraft upload speed hits about 10mb max for about 20 seconds, then drops for a few, back up to about 8, then in-game i get the infamous "an error has occurred" error message.
I've also created a new world, all default just create, create , load in - locally. that uploads instantly.
I've checked the world I want to upload (about 188mb) there is a custom resource pack under 'My Packs' but the only active pack is 'Global Resources'

EDIT: All working - changed upload limit from 35mb/s to 3.5mb/s and it uploaded!
