I also had this problem when I got a new Epson XP-15000, going into Page Setup immediately crashed Lightroom. I was ready to send back the printer, but for a totally unrelated issue I needed to reinstall Ventura on my Mac Mini.
So I erased my drive, installed Ventura, added the printer via the XP15000_Lite_64NR_NA.dmg package, installed Lightroom, and re-imported my photos into a brand new catalogue. No more crash when going into Page Setup.
Fortunately, my Lightroom is set to always write any changes to an .xmp file, I didn't lose my edits when I created the new catalogue.
Granted, this is the nuclear option, but in now works without issue. If I didn't have the other issue, I probably would have tried to un-install Lightroom, re-install, and rebuild a new catalogue. At this point I don't know if that would have worked or not.
