Can I temporarily disable beta Minecraft?

Hi, I'm Luis a Xbox user just like you. Thanks for reaching out us here.

Yes, Players, can opt-in and out of Preview from the Xbox Insider Hub app

Be sure to back up your worlds first! Open the Xbox Insider Hub app and unenroll from Minecraft Preview. Uninstall Minecraft. Reinstall Minecraft from the Microsoft Store app.

This usually happens in the minecraft beta version. If you have beta enabled, disable it on the xbox insider hub and reinstall minecraft.

Ensure that you are on the most recent version of the Xbox app and the Game

Microsoft Store app > Downloads > Get updates/Update all

Ensure that you have updated your PC to the most recent version of Windows, including optional updates

PC Settings > Windows Update > Check for updates > Install

Open the Xbox app on PC > (the game) >Manage > Files > Verify and Repair

Sign Out of Your Accounts (Xbox App and Microsoft Store App):

Open the Microsoft Store by pressing Windows Key + S, typing Microsoft Store, and selecting App Settings.

Click on Repair and then Reset the app.

Repeat the same process for the Xbox App and Forza Horizon 5 Game

Restart Your Device:

After repairing and resetting both apps, restart your device.

Sign back into both the Xbox App and the Microsoft Store using the same email.

Let me know if that fixes the issue. Thank you!

I am guessing your friend is enrolled into the beta for Minecraft through the xbox insider program

Actually, they sent the beta out to non beta users, and as noted above if they tried to load in their old world, it may be (temporarily) lost. As of 30 minutes ago (via the xbox feed) they advised those who got the beta to uninstall it and reinstall Minecraft
on their xbox.

Unplug it. That would be the only way.
