My iPod Classic won't sync after installing Tahoe 26.0

For years, I have routinely synced my iPod Classic with Music on my iMac desktop.

However, it appears that after installing Tahoe 26.0, the syncing process with my iPod Classic is no longer working; i.e., the "Sync Settings" button will NOT take me to the relevant screen to sync the device!

QUESTION: ...Is anyone else experiencing this problem?...Is there anything that can be done about it?...

[NOTE: I also have an iPod Touch, which I have been able to sync without any problem. And with respect to the iPod Classic, please note that I have already rebooted (i) the iPod Classic, (ii) the Music application, and (iii) my iMac computer, none of which helped! Also, the cable is clearly not an issue because (i) I have been able to sync my iPod Touch, and (ii) the Music application on my iMac is recognizing my iPod Classic device.]

Thanks so much!

(P.S. ...I am apprehensive about carrying out a full restore of my iPod Classic for fear of disabling the device entirely...But I can't even do that because I can't get beyond the "Sync Settings" button!...)
