macOS 12 Public beta: can't install because of an error (system preferences: Software update)

Hello everyone! I have a small issue with the update process in my MacBook Pros (both of my 17,1 and my 14,1) and also with my iMac 18,2. it's saying that I have a problem and that all. the first try was on my MacBook Pro 17,1 M1 (running 11.4) I followed the instructions from last year and the year before downloading the Public Beta Profile from the apple Public Beta website Installing it Going to system preferences Clicking on the Upgrade button Waiting for it to finish starting the installation proces) but this time it just after the download gave me a message: "cannot be installed because of an error." so I restarted the system and tried again but this time it didn't even let me download the installer from the system preferences it just said there: Big Sur public beta so I tried on my intel MacBook Pro (14,1) and the same issue so as my Final attempt was using my iMac 18,2 and sadly the same error.

Dose it happened to somebody? and if you fixed it how?

Thank:)

restart your Mac when you see this message but before you restart the iMac MacBook etc go to launchpad and look for macOS 12 installer open it and if it doe set open restart your Mac.

I talked to Apple support about this and they said that the one being used is an outdated beta and a new ones being tested. Although I think macos12 is being real eased tormorrow so that’s the final beta.
