Apple Devices app on Windows fails to find my Apple device backups

I have backed up my iPhone on my Windows machine. When I launch the Apple Devices app, it says that the iPhone has never been backed up and the "Manage backups" button is grayed out. Yet the iMazing app shows that the backups are there.

Backups via Apple Devices used to work.

It is probably worth noting that C:\Users\<my ID>\Apple\MobileSync\Backup is a junction link to a folder on another device (with much more space than C:). However, Windows Explorer has no trouble navigating to that folder.

Moreover, if I back up the phone manually using Apple Devices, the backup appears to work fine, in the sense that it takes time, and it writes files into the folder that is a target of that junction link. It is just a matter of Apple Devices failing to report that any backups exist for this iPhone.
