What version of photoshop are you using?

I don't know, but far as i can tell windows 10 itself won't display thumbnails of those files in explorer, which is what photoshop uses for the File>Open dialog.

In order to see the Canon 5d mark iv cr2s in windows explorer you need a third party codec such as this

Adobe Bridge should be able to displays thumbnails of those Canon 5d mark iv cr2s.
