Since you have received no suggestions, I will share with you an experience with the same error and crash, but in Apple Mail. It may be that Photos behaves similarly and lead to a resolution for you.
Mail remembers the last state when you quit (or it crashes). Specifically, which e-mail was highlighted/selected. If this e-mail is corrupted in some way, Mail will continually crash on opening. The solution is to hold the shift-key while starting Mail, which puts it in a "neutral" state on opening. Then find (yah, how?) the offending e-mail and delete it. This has worked for people to whom I have suggested it.
It may be that there is a corrupt Photo in your group that causes the crash, and every time you work with it, bam!
This could be a long shot, and how you might find the bad (in what way??) photo is anyone's guess, but given the lack of other suggestions posted here, this might give you someplace to start.
On a Mac since 1984.
Currently: 27" iMacs, Macbook Air, macOS 10.14.x,; iPhones, iPods and iPads galore!
