Can't modify image in Develop; message No photo selected"
Symptom: I can locate an image in Library/Grid view. I'm sure the file is there (I recently ran Find All Missing Photos, and only 30 of 114K images were missing). I go to Develop mode. The image displays. I change a slider (I picked Shadows), and image disappears, replaced by message "No photo selected".
Background
I'm on MacOS 15.1, LRC 14.0.1/Cam Raw 17.0
Catalog on external 2TB SSD; images on external 6TB HDD
I recently moved disk drives around. But ran Find Missing to make sure LRC was seeing the drive. It is. Only 30 missing of 114K.
I recently built Smart Previews for all images. Took several runs as there was a power failure. But catalog has passed the validity check and optimization consistently. No errors reported.
I have made sure that LRC has Files and Folders access in MacOS 15.1 (24B83). I tried granting Full Disk Access but this did no good.
I'm at the end of my capabilities to address this.
1. Library/Grid view:

2. Upon entry to Develop

3. After modification on Shadows slider

4. Just to clarify: Grid view of Missing Files folder showing a) only 30 of over 114K images and b) missing badge shows as expected.

I would appreciate knowing if I should have uploaded the image files rather than pasting inline.
Thanks!!
