when I imported photos they do not show up

[shobur24550055mdkn]

when I imported photos they do not show up in the Library view and only show up in the Develop module if I click on a specific photo. All of my existing photos show up correctly, it's only the new imports that do not show up. I looked in finder and the pictures are in the correct folder and the metadata does show correctly in the Library module, but all I see are gray boxes, no photos.

Looks like the preview cache has been corrupted. Try deleting it, as described in this help article:

After deleting it, LR will regenerate the previews on demand, which, depending on your photos and the speed of your computer, may cause it to be a little sluggish.  You could go to All Photographs, select all photos, and do the menu command Library > Previews > Build Standard-Sized Previews and let it run over night.

Please provide the full path/folder and file name of one of these photos.

Not just this folder but every folder and every photo has this problem

Using a period (or dot) in the folder name can cause this problem.
