DNG scans via Silverfast not importing to catalog

[GuapSoto]

Hello,

I recently noticed when scanning some 120 negatives with my v600 & Silver Fast 9 the DNG files do not properly import to my LrC catalog. I scan them as 48bit/16bit raw dng files to convert in LrC with the Negative Lab plug in. I have done this for a few years now and never had an issue until yesterday when importing some scans. 

LrC will set up a preview of the file but won't show a numerical presence in the side menu. Any ideas?

Update: I tested if it would also act this way with RAW files from my camera. Sure enough my RAW files from my Canon R are also not being recognized. I do get a preview of the files but I cannot edit them. I have had no issue with RAW files prior until now. I haven't changed any settings recently to my catalog or import settings. Any ideas on what may be the issue? Thinking of moving to a prior version of LrC to see if that may be the issue.

Can you share one of your files?  I don't think it is a Lightroom problem.  Instead, it might be an operating system problem.  Maybe "write permissions" were changed in an update.

Try this: open your catalog folder and trash the 'catalogname helper.lrdata' file. Then start Lightroom Classic again and see if that solved the problem.

To build on Johan's reply, your screenshot shows a negative count of photos for a folder, a sure indicator that the Helper.lrdata got corrupted due to a LR bug and needs to be deleted.

I ended up finding out the catalog was corrupted and ended up creating a new catalog, with the new catalog I can import RAW files no problem! I was considering making a new catalog so I guess it happened at the best time. 

Went through Adobe's support chat and had an agent remotely test the issue.

Most likely simply deleting the Helper.lrdata file would have fixed this issue without needing to create a new catalog.
