corrupted Photos Library, no support email?

I scanned a smallish Photos Library (under 8000 items). DPFP seemed to hang for quite a while. I came back to computer and followed instructions: mark and then trash marked, opeienning Photos when I was asked by the screen. Photos said my library could not be opened and attempt to repair it didn’t work. Looking for an email for support, could not find, only India based phone number… Obviously I hate an app that corrupted my perfectly fine library on first use...
