Find untagged items suddenly stopped working. It was working perfectly fine as I would find untagged photos and started applying keyword tags to them. I can view these photos I haven't tagged yet in All Media and verify that there are no tags associated with the photos but they still won't show when I find untagged items. There are no smart tags or keyword tags or album tags linked to these photos. Very frustrated - help! I have Adobe Photoshop Elements 2019.
The only thing I can suggest is to try resetting the preferences file. Immediately after launching the program, press Alt+Shift+Ctrl (Windows) or Option+Command+Shift (Mac). A message should pop up asking if you want to delete the Settings file. Answer OK.
