I'm stuck in the beta. I've tried lots

I've joined the rtx beta, and was amazed at the visuals. Shortly after, I learned multiplayer is not allowed in beta, so I tried to opt out. I've un enrolled, uninstalled on many occasions, tried the command prompt "Get-AppxPackage -allusers *minecraftUWP | remove-appxpackage -allusers*" I have logged onto the account that owns minecraft, and nothing has worked.
