report the issue in the insider hub app. Then you can uninstall and reinstall
your profile on the console.

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.

You said you have removed the console from the insider hub, but have you removed it from the program or just uninstalled the app? If you have just uninstalled the app, then reinstall the app, goto settings and unenroll the console from the preview program.
Once you have done that the console will need to download the public update. After that you shouldn't need to update again until the next public update is released.

Hi LeafLegends07,

Having a corrupted profile is one of the possible reasons why your account is stuck in a Beta version. To help you resolve this concern, I recommend that you uninstall and reinstall the Xbox app from your Windows 10. After you op out from the Xbox Insider
program you need to sign out your account from the Xbox app and then uninstall and reinstall the Xbox app. To do this, you may follow the steps below:

1. Click start, and then type Windows PowerShell on the search box.
2. Right-click, and then select Run as administrator.
3. Type the following command to uninstall Windows Store: Get-AppxPackage xboxapp | Remove-AppxPackage
4. Hit Enter.
5. Launch Windows Store again and download Xbox App.

After uninstalling and reinstalling the Xbox app, you may need to uninstall and reinstall the game as well.

Kindly update us with the results.

Hi, thank you for your reply. To clarify, should I uninstall/reinstall only Xbox Insider Hub? Not Xbox Live App? Also, do I uninstall/reinstall Minecraft Windows 10?

Hi, Download the Xbox Insider hub app from the Microsoft store, Launch the app, On the main landing page, select Insider content. Under System, select Xbox One Update Preview. Select Join or Manage. Choose a Preview ring from the available selections.
Alpha/Alpha skip ahead may be greyed out, as those rings are invite only.
