Question
"Lightroom has encountered problems reading this photo"
This is happening constantly lately, both with files on external disks, and the internal SSD. I'm not sure yet, but I suspect it may be happening when I sync-settings or copy/paste settings with subject and/or background masks. I'll sync the settings across 10 photos or so, and a couple of them might get that ! mark on it, and I have to reboot LR to clear it.
