Recently I did some import from cameras and a newly bought Gopro, and MAYBE A HINT, when I connected Gopro to Mac, Photos automactically opened up its window and tried to import videos but only left me a permanent freezing, so I did forced close to Photos..maybe at that time the library was damaged..
