Just got this message while playing Control. Selecting break froze the game. (On alpha skip...

I had this one also i think it's only availble for some xbox insiders in the highest build (alpha skip ahead) i just deleted the message and never replied to the person who sended me that message

That's a possibility. I'll message him to see if he's in the alpha skip ahead.

I'm in the regular alpha wave.

I believe you can re-enroll but I don't believe is guaranteed to be in Alpha still.

If I deregister the Xbox X out of the program, will it also deregister the Xbox One?

Originally the Xbox One was in Skip-A-Head Alpha. I purchased the Xbox One X, selected registration for Alpha Skip-A-Head, and it was automatically enrolled in the Alpha Skip-A-Head program.

I got the impression it is tied to the user who not the product. Hopefully someone in the program knows for sure.

Well if he's in the insider programn then he got a update today had the same issue the alpha & apha skip ahead builds are broken for 50% of the people that are ih that group so don't update your console if you're in alpha or alpha skip ahead

There is only a limited number of free slots in Alpha/Alpha Skip Ahead.

If someone in Alpha/Alpha Skip Ahead leaves, or is removed due to inactivity, participants in Beta are invited to Alpha. However, Beta participant invitations are sent out to those, that leave valuable feedback, find bugs, and are most active in the beta
group.

So it's not how long you are in the program, but how valuable your input and bug reporting was in the past.

Added to the fact that invitations are only sent out if there is new room in Alpha, you might have to wait a while to get invited. Just provide good feedback and be patient.
