can't open any of my files

When trying to open a file whether it be a pdf, jpeg, zip or trying to install a new font, I get this error

“INSERT FILE NAME” is damaged and can’t be opened. You should move it to the Trash

(It says the actual file name, but that's the message I get for everything I try to open.)

The file is most certainly not damaged as I can install fonts by dragging in to FontBook and open files thru respective program.

a little history of when this started:

I recently got a new battery installed thru Apple and they also changed out my logic board so I had to reinstall everything. The file error started after the reinstall and happens to all files, new and pre-service.

I used Time Machine to reinstall all files.
