Lightroom freezes when I Update All AI masks for a large number of photos

Hi all - I'd love some help here as I'm struggling to resolve this issue. For context, I send wedding galleries to an editor and she does her edits then sends me back the catalog. At that point her masks and spot removals don't show up unless I do a mass update of the AI settings. I usually go into Library Mode - Photo drop down -  develop settings - update ai settings, which usually works fine to update all that she's done on the images. However lately every time I click that, Lightroom freezes and I have to exit out via force quit applications because I can't get it out of the frozen updating of the ai settings pop up box. Can anyone shed some light? I can't get her edits to populate and it's a major headache. Thank so much
