When I clicked on Minecraft to launch it, the update started and for some reason it went into beta. I don't remember joining it, so I checked Minecraft for Windows 10 in the Xbox Insider Hub preview and it was "joined." Even after doing the instructions on aka.ms/minecraftXIP on how to revert a beta to a release version, once Minecraft was I've tried downgrading, updating, uninstalling, and reinstalling Minecraft, but it still didn't make it to the release version.
