I try to authorize my new laptop on the music app, and it says I can't because there are already five computers authorized. The apple site says to go to the store in music and get settings. From there you should be able to de-authorize particular computers. But in the settings, it only lists one computer as authorized, and there's no "deauthorize all" button.
MacBook Air, macOS 14.3
On your Mac you can try System Settings > Click on your Apple ID > Click on Media & Purchases > Under Account click on Manage. There you may see the Deauthorize All button.
Otherwise can you access a copy of iTunes, or Music on a different build of macOS? From there you should be able to reset your authorizations and start over. Alternatively reach out to Official Apple Support and ask for their help to reset your authorizations.

I have the same issue, no deauthorize button(Sonoma 14.3.1). Luckily i have an old MacBook Pro lying around running Sierra 10.13.6 that still have this option so I could deauthorize that way.
and this is why I hate apple
cannot find the deauthorize button, only says 1 computer authorized
