When ever I run into problems opening an Application that I know worked in the past is this...The message was "Photos cannot be opened because of a problem".
I've just created an account just to say thanks for this post, my iPhone was not recognized by iTunes but others did, and if I connected to another computer it was recognized with no problem, I wiped it, I reinstalled High Sierra and a lot many things but this software "Pacifist" did the trick, luckily I had a flash drive with the OS (since it is no longer available as a purchase in the AppStore) ran the installation on iTunes and the problem was solved.When ever I run into problems opening an Application that I know worked in the past is this...
I open the installer app "Install macOS Sierra" in Pacifist and just select and reinstall the app with the problem.
For me this has always worked to solve the error.
