Can't leave Minecraft beta, it's stuck. Tried almost everything.

I tried everything, lots of users reported this issue on reddit, i just can't leave the beta. it's stuck and now i can't play online since i am on a different version.

I tried to rejoin the beta and leave it again > still stuck 

I tried to follow this > still stuck

I tried to totally delete my xbox insider account > still stuck

I tried to recreate insider account > still stuck

I tried to install it on another machine > still stuck

 

This is starting to get really annoying.
