cant leave windows 11 insider program

Hello,

i cannot leave the insider program. Im in windows 11 beta channel right now. If i try to leave the proramm by settings -> windows update -> windows insider program i have two options. I should be able to choose to leave the program with the next windows release, but this option is blurred out and i can not interact with it. The other option is the link at the bottom, which redirects me to a microsoft website. After logging in, it also tells me i can not leave the program now because my mail adress isnt registered. But u dont have another mail adress.

I already contacted the support about that, the case number is 7034906605.

We tried to create a new user and leave the program by this, but it also didnt work.

I also did a windows reinstall with keeping my personal files and data.

I would like to get around this issue without having to completely reinstall my windows because its a long process.

Is there any way you can get my PC out of the beta insider program please?

Greetings,

Johannes.
