I'm having the same issue on 14.1 (23B2073) and I tried the solution above, but I can't find the /System/Library/Image Capture/Devices/PTPCamera. If you drag the photo separately to your Album, you will an error message saying "they may be in an unrecognized file format or the file may not contain valid data". Then I started to doubt my photo was damaged due to unknown reason during transferring. So I duplicated the file, and import the duplicate file, and it works! This is definitely an issue which needs more attention.
