Imported photos now end up in a virtual copy of my D: drive

[SimonB1960]

As of a few weeks ago, when I import photos into Lightroom Classic 9.2.1 (CR 12.2.1) the photos now end up in a virtual copy of my D drive.

The imported files are physically copied to the correct drive and folder, but Lightroom seems to see it as a different drive to where my existing photos are stored.

And so when I click on the library folder for my existing photos, the newly added ones are not present, and when I click on the second copy of the D drive (in the library list) the newly added photos are there.

I can "move" the photos (physically they are not moved) but this is a nuisance. 

What is going on?

Sadly, it's a fairly common issue, especially on the Windows platform. That being said, this Adobe Help document should help you resolve the issue https://helpx.adobe.com/uk/lightroom-classic/kb/lightroom-displays-same-hard-drive-twice.html

Thanks for this help. It seems to have put the drive back into normal
configuration, for the time being.

Is it known what causes this problem? Was it one of the many updates of LR
Classic CC or is it just an unknown bug, or an unknown bug in Windows?

Or is it a plugin or something. I think I installed the Helicon photo
stacker including LR plugin about the same time that I first noticed the
two copies of the same drive. But I disabled the plugin and it did not fix
the problem.
