Thumbnails not showing

I’ve been using Digikam ver. 8.6 for a while running Ubuntu 24.04.2 LTS without any issues. A couple of days ago I started getting blank thumbnails with no image. If I double click on the blank area the photo will open in a reduced preview mode. If I go back to thumbnails view it’s still blank. I’ve tried re-building the database with no improvement.


I’d appreciate any thoughts/suggestions.
Thanks,
