Beta vs Official: Confused About Version 12.22

Hello everyone, I participated in the beta program, going through the various versions in recent days until I reached 12.22. This version is also an official system update, and I tried to install it.

I’m told there are no updates available. Is the beta version the same as the one officially released? Or is the beta, despite having the same release version name, still different, and I’m having issues with the installation?
