Lightroom Classic "No photos in selected folder"
Lightroom Classic 9.4
Camera Raw 12.4
Windows 10 1909
I scanned some photos into a new sub folder into a folder already in my catalogue, tried to synchronize, Lightroom hung and now my folder view seems broken.
My catalogue is showing all my photos. I can click on all photos, search and select and find a photo.
However in folders. if I go to any folder I get "No photos in selected folder" although the files show in Windows explorer and there is a correct count of photos.
If I right click and select syncronize folder it hangs with (counting ...) after each line and the Show Missing Photos and Synchronize buttons stay greyed out.
If I uncheck everything except import new photos it gives me the synchronize button but even on small folders hangs for an hour.
Waht si wrong and how do I fix it. I use catalogue metadata not sidecar files, I can't afford to lose all my key wording.
