Lightroom classic 8.2.1 - Photos have read-only access

Photos have read-only access

I upgraded from Photoshop Lightroom 5.7 to CC subscription Lightroom Classic 8.2.1.

My images are stored on internal hard drive.

With Lightroom 5.7 I have no problem to write metadata into photos. However, when I try the same with Lightroom classic 8.2.1, I'm getting error - photos have read-only access.

But when I check photos, the check mark for "read-only" is unchecked.

Permissions - I'm the only user (administrator), and all of principals (windows 10) have full access to image files.

After trying a lot of things (changing permissions, installing/un-installing lightroom, creating new catalogs, ..) I finally figured out what is the problem:

My image files are on virtual drive. I created virtual drive using DOS command "subst" (historical reasons; subst 😧 G:\...\....\....\Photos ).

Lightroom 5.7 doesn't have any problem with such created virtual drive, can write metadata into jpg files, but Lightroom Classic (newest version) can't. Always getting message "Photos have read-only access".

If I dismount the virtual drive and point the Lightroom Classic 8.2.1 catalog folder to the real location of photos, then the metadata writing works.

So my questions are:

• is this a bug in Lightroom Classic 8.2.1 that it sees jpg files on virtual drive as "read-only" or is this intentional? Lightroom 5.7 has no problem with it.
• Is there some way around this issue so I can continue using my virtual drive? (a lot of my applications are dependent on it).
