Vintage iPod no longer recognised on MacPro after Sequoia installation

Ipod not recognised and cannot be found through Finder nor AppleMusic. Group chats would seem to indicate that this is not a problem that can be rectified atm. The4 iPod has had a thorough service after the problem arose but this has merely confirmed that the iPod itself is working perfectly. Unfortunately all my songs have been deleted from the iPod although these remind on MacBook Pro Music hard drive.
