Apple Photos – Photos couldn't be copied because you don't have permission to access

I'm having the same issue. I'm trying to combine all my images from many different files, libraries into one library and get the same message. Even if I drag the individual image to the desktop.

Does anyone have any ideas on how to fix this?

thanks

Have the image files been in nested folders, and you tried to import them from these folders?

This is problematic, if you have two files in the nested folders with the same filename, the import can fail with this error message in the first versions of Catalina. Importing smaller groups will reduce the likelihood of importing duplicates within the same Import session. I can no longer reproduce this buggy behaviour in macOS 10.15.4..

Which version of Catalina do you have installed? Photos 5 is a part of macOS 10.15 Catalina, but the system version given below your question is macOS 10.13.

Could you please give us the full version number of the system version, so we can see, which update you have installed? It would be helpful to know, if you still have been running macOS 10.15.3 or already updated to macOS 10.15.4. The reason I am asking is, that I only had the problem you have been describing in the early versions of Catalina, and have been hoping the macOS 10.15.4 update has fixed it. But if you are also running macOS 10.15.4, the bug still persists, which would be very disappointing.
