Can't access or change iCloud Storage downgrade options on MacBook Pro M2

After clicking downgrade option for this function in System Settings, I get a pop-up that says I can't do that now, wait a minute, and try again later. I tried this first thing after doing a Recovery, reinstall of macOS Sonoma -- l cannot get rid of the pop-up so I can change my iCloud storage settings using the Mac. But, oddly, I can do this on my iPhone. But that is not sufficient. I want the laptop to work properly.
