Why does Minecraft keep crashing when syncing old worlds?

Update - I mananged to sync One Minecraft save and it is not where I left when I last played. This save is a good 3 months old. Why are these saves old and not new?

This cloud stuff is broken as hell

Are you talking about a Minecraft world? Also, what version [Xbox one(the old one) or bedrock (the latest one with cross platform)]?. Usually if you're connected to Xbox live, all worlds sync up to the cloud, if you're playing on Minecraft Bedrock edition,
when you click play, there should be an option at the bottom to sync old worlds.

Hey ahero10 -

Does this issue occur with other on-disc games or just Minecraft? If it's just Minecraft, can you detail the issue more specifically please? When does the crash happen, when you insert the disc or when you start up the game? Are you provided with an error
code? If so, please give us that code so we can look into it. (Error code would look like XBOS-0000 or 0x00000000.)

Keep us posted!

Try reinstalling the game.

You can use the Minecraft Realms standard or try the steps below first when transferring worlds.

In Minecraft (Bedrock Version), select the Sync Old Worlds button at the bottom of the worlds list in the Play menu. This finds any worlds on the device from the Minecraft: PS4 Edition and displays them below the button.

Select any of the worlds that are displayed to convert it to the Bedrock edition.

After conversion, the world will show up above the Sync Old Worlds button, along with the rest of your Bedrock worlds.
