Photos crashes when exporting slideshow

[LotusLord]

I've never actually tried this previously but we're trying to export a slideshow of photos, ideally with a song or two, from Photos to display at my aunts memorial service. I'm running 10.15.4 right now on a Mac Pro 5.1. When I select any location to export the file to, be it the local SSD or secondary hard drive, or a flash drive, the app immediately crashes. I'm a Windows guy by trade so this has me stumped. A portion of the error I get at crash time is here:
