¿Está tu Minecraft: Education Edition en la última versión? (1.14.50) si es así, podría ser un problema de cuenta. Si no compró Office 365 en su cuenta, no le permitirá usar Minecraft: Education Ed...
That must mean an important .json file is missing and MC:EE cannot read it. I guess you cannot use the pack because there is no manifest.
That isn't possible unless they allow server hosting.
The camera is an entity that is impossible but that would be cool.
Might be an internet issue. Check your internet and try again.
Sounds like none of your work saved. You might have to redo all the work and make sure it saves. If it doesn't work then you should contact microsoft.
Because it's how you are supposed to create worlds and join worlds. If you didn't have to sign in that would be a major security issue because random people can join other's worlds.
Sorry but no. It's such a pain that worlds are not cloud saved but at the moment there's nothing we can do. :(
