Minecraft Bedrock Edition worlds take forever to load, also syncing too?

Hello UngaBungaBill, I hope everything is going well!

Thank you for reaching Microsoft Xbox Forum support!

I highly recommend following the troubleshooting steps here:

After each step try to see if the issue is fixed!

First, hold down the power button for about 10 seconds, until the console shuts off, then unplug the power cord and wait for 2-3 minutes before plugging it back in and turn on the Xbox.

If the issue persists, please select System > Settings > devices and streaming > blue ray > persistent storage > clear three times > restart console.

If you are still encountering the same issue, please select System > Settings > System > Console info > Select Reset console > Choose Reset and keep my games and apps.

If you are still having the same issue, it’s possible that the local save for the game has become corrupted. If so, deleting the local save and re-syncing with the cloud might correct the problem.
First, delete the local save:
1. Press the Xbox button to open the guide and then select My games & apps > See all > Games.
2. Highlight the game title, and then press the Menu button on your controller.
3. Select Manage game and add-ons > Saved data.
4. Select Delete all to remove the local save of this game, then follow the prompts.
After you delete the local save, restart your Xbox:
1. Press and hold the Xbox button in the center of your controller.
2. Select Restart console, then follow the prompts.
After you restart your Xbox, re-sync your saved games to the cloud. Your saved games are automatically stored in the cloud while you’re connected to Xbox Live.
Try playing the game again to see if re-syncing with the cloud corrected the game problem.

I wish you a lovely day, and I hope this helps you out!

Kind Regards

Stay safe, and happy gaming!

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.

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.

You can sync worlds from Minecraft: Xbox One Edition to Minecraft for Xbox One (bedrock edition) in game,
but you cannot sync the content across, as far as I know.

good night

In Minecraft (Bedrock version), select the Sync Ancient Worlds button at the bottom of the world list in the game menu. ...

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