For good measure, I am getting the exact same thing when trying to import photos from my Blackberry KeyTwo. Same hang at the same point (it's just at '1009 items found so far'). Last time I did an upload to my desktop (last week) it was absolutely fine. Probabaly need to check that now too.
I was also trying to move the Photos app so that the photos all sat in my OneDrive area, rather than on the hard drive. When I clicked 'Move' from the Settings/Apps area no go, nada. Didn't do anything, just ignored me. I'm going to try a repair, however, bit time consuming... These things should just work, shouldn't they?
