reinstall it and install it again.

Simple! uninstall minecraft (go to the start menu, right click minecraft, uninstall) open the insider hub (when it comes back online) go to insider content, Minecraft, and click unenroll the same way you enrolled in the beta. then reinstall minecraft.

Have the same problem. Unenrolled from beta testing in Xbox Insider Hub. Restarted. Reinstalled Minecraft. Open Minecraft. Is beta. Uninstalled Minecraft, waited 24hrs, restarted. Installed Minecraft from store. Still beta. Have multiple licenses of this
game to play it with my kids who are under 13 and thus cannot join the Insider hub. I can't use the beta version to play with them so this is keeping me from enjoying this game. please fix.
