Gwenview slow to open

[wartnose]

I had been on 18.04 forever. Firefox and Chrome didn't like it anymore so I decided to test 24.04 in a virtual machine. Worked so well I just lived in the virtual machine for a while. I finally bit the bullet and did a clean install on a new SSD. Mostly impressed but Dolphin is a bit slow to open and viewing images in Dolphin folders is really slow because Gwenview takes 15 - 20 seconds to open. Any suggestions? By the way I did save my virtual machine and I moved it to the new drive and tested Dolphin and Gwenview in the virtual machine and they both open quickly. Thanks
i5, 16GB, 2 TB Teamgroup SSD. Kubuntu 24.04

My first thought always is to see whats happening with the application - so open Konsole and launch Dolphin from there and see waht messages show up in Konsole. It might offer a clue.

This must be an issue from time to time because a Google search "Gwenview slow to open" offers a lot of suggestions. As per one suggestion in Configure Gwenview- Advanced, I unchecked "History: Remember folders and URLs". I rebooted and thought things were fixed, but when I let the computer sit idle and it went to sleep, when I woke it up Dolphin and Gwenview were again slow. I then checked "Thumbnails: Low resource usage mode" because this avoids saving thumbnails and I read this might be an issue. So far so good, but per your suggestion I'll open in terminal next if it doesn't stick.
