PSE 20 Full Back up Error

When I am done doing a Full Back up, I get a pop-up window similar to this below but with a different file name every time:

_________________________________________________________________

Elements organizer

Error encountered while writing file(s)

C:\Users\Ramsey\Pictures\...\2020111_083711.jpg

                                                                                               OK

  _________________________________________________________________

This has happened 5 times. Each time I do a search on the file, copy it to the desktop, delete the file in PSE and run a Full back up again only to get a new file with the same message.

When I run “Find” >  “All missing files”  I get nothing.

When I run “Find” >  “Items with unknown date or time” I get nothing.

Additionally I have found that when I go to an identified file (*.jpg)  in “file explorer” and try to open it I get a “permissions” error.

I have given “read/write” permissions to all files in the “Catalog” containing my photo files. After giving full permissions and running a Full Backl Up I still get the same message shown above. 

As a result I am unable to do a full back up.
