Stuck On Activate Mac....

I have done this before and have never had a problem. Was having some problems with a new macbook air and a 2 year old mac studio. Both computers after hard drive erasure go to activate and all I get is failed to activate. I have strong wifi and I even plugged in ethernet cable for strongest possible connection. This is so annoying and frustrating as I am not a newbie to how this works. What am I missing here. I already had to send my new macbook air back to apple to reactivate it. I upgraded to Sonoma during a tech session with an apple technician when my macbook air was stuck and he said I needed to upgrade my mac studio to the newest version to download a particular mac program called configurator to try to get my macbook air going again before sending it back to them anyways. I CAN NOT STAND SONOMA and I wanted to put my mac studio back to Monterey and then time machine all my programs back into it but again am stuck at the won't activate screen !!!!! I am also using a bootable usb with Mac Monterey on it as That is the operating system I liked. I wanted to put it on my macbook air but am afraid if I wipe the hard drive again to try that I will run into the same problem again and it will not activate. WHAT AM I DOING WRONG HERE ???????

If someone knows any way for me to get my mac studio up and running again I would be eternally thankful. NOTHING WORKS as far as keyboard shortcuts while booting and turning on ETC..... Thank you for your time
