Files in Desktop cannot be edited in macOS Catalina I cannot open, change, edit, write, or read any of the files in my desktop. 

I have pictures on my desktop but when I attempt to open them, this error appears: "The file “FileName” couldn’t be opened."

Same with documents and other text files.

This includes files in subdirectories underneath Desktop as well.

All the permissions of Desktop and read and write, in terminal I can move and edit text files, but I cannot do it within the UI itself.
