FWIW:
.... looking at my Mac... High Sierra, 10.13.1, I have PSE 12 installed on it - I no longer use PSE, since I have access to Photoshop - BUT PSE 12 still runs under High Sierra and it was a 64 bit application.
Now, initial tests came up with an error trying to launch it from Photos EDIT WITH - giving a file or URL issue with the passed image. PSE 12 would open the image, a DNG file, as a raw file with ACR from PSE 12.
Yep! That's exactly the error message I get. I can use PSE 15 only if I select the photo, export it to pictures, go to PSE editor, open, select the photo from pictures. After working on it I have to save it to Pictures, go to Photos, import it from pictures. Maybe I'm lazy and just have to "get on with it". I got spoiled using an extension.
