Question

Lightroom Classic

Hello. I am experiencing an issue with Lightroom Classic.

In the Library module, my photos are not displaying. Instead of thumbnails, I only see gray placeholders.

I have already tried the following steps:

  • Generated Standard and 1:1 previews
  • Deleted the Previews.lrdata file
  • Reset Lightroom preferences (Alt + Shift on startup)
  • Restarted the application
  • Verified that files are not missing (no "?" icon)
  • Tested with a new catalog (the issue persists)

Additional details:

  • File format: Sony .ARW (RAW)
  • OS: Windows
  • Catalog stored on local disk

The problem seems related to preview generation or RAW decoding.

Please advise on how to fix this issue.

I can provide screenshots and sample files if needed.

If dj_paige’s suggestion doesn’t help, then please do the LR menu command Help > System Info and copy/paste the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.

Also, ​@Nazar123 the title of your post should not be the name of the software; it should be a description of the problem in a few words, like “Thumbnails are grey in Library”. The Adobe community would be a much less useful place if lots of posts were entitled “Lightroom Classic”.
