Can't update books

I am not able to update existing books. This includes books that I have previously been able to update (meaning that I don't think it's a corruption of one book file). When I attempt to do updates or book-level application of show/hide conditional text, the application crashes without any meaningful error message, just "Adobe FrameMaker 2015 has stopped working" (screenshot below).

System info: Windows 10, 64-bit

FM version: 13.0.5.547

Stuff I've tried (to no avail):

• Opening and updating an older book (that I know I was able to update and publish to PDF within the last two weeks)
• Opening all docs/chapters within the book before updating the book
• Moving the book and docs from C drive to another (local) drive
• Moving the book and docs to a network drive
• Creating a new book and adding docs/chapters into the book one by one
• Saving each file to MIF and then opening them to rebuild the book
• Restarting my machine
• Showing all conditional text
• Copy and pasting text into entirely new docs/chapter files

I was able to create a new book from the prefab templates, add two paragraph markers and then create a TOC (that I could update). But I cannot update TOCs for or generate any PDFs from any of my existing work.

I am at my wits' end. Does anyone have any suggestions?
