Lightroom Classic 15.2 not showing thumbnails after import, only if you do a restart, then you see the thumbnails

Hi everyone,

I’ve been experiencing an ongoing issue with Adobe Lightroom Classic, currently on version 15.2. This problem has been happening for the last three updates, not just this latest one.

After importing RAW files, the thumbnails do not appear in the Library module. The folder and total file count display correctly, but the preview area remains blank.

The only workaround that consistently works is fully restarting Lightroom. Once I relaunch the program, all thumbnails appear normally.

System details:

• Lightroom Classic version: 15.2

• Computer: Apple M3 Pro

• Memory: 18GB RAM

• GPU acceleration: Set to Auto

• File type: RAW

• “Generate previews in parallel”: Enabled

• Storage: [internal SSD or external drive]

This happens every time after import. Restarting fixes it temporarily, but having to do that after every import is not practical.

Has anyone else experienced this over the last few updates?
Is this a known issue with Apple Silicon machines?
Is there a more permanent solution besides restarting the app?

Thank you in advance.
