"Failed attempting to join realm" after chunks unavailable/black marks on map
While playing, chunks didn't load, squares on an explored map became black, which behaved like they didn't exist (like air, not like a texture/graphic glitch). Then after logging out, I can't log in again.
Environment
Windows 10 - Realms server, affects multiple platforms/users.

Realms server is still not working, attempted to reload from backup, reset, reload, reload from older backup. No matter what I do I still can't login from any device.
Still unable to join realm
