Hi,
I'm working with a friend who has WORD 2019 on Mac OS Ventura 13.6.9


He has a large docx file (2000+ pages, 15.7MB) which is exhibiting the following behavior:
- if his TOC does not have hyperlinks activated, he can export to PDF with no issues
- if he activates hyperlinks in the TOC (\h in field codes), the export times out with the error "can't export file". There was a problem connecting to the network" - this failure occurs after several minutes of apparent effort to export the document
- if he reduces the size of his document <600 pages, the export with hyperlinks works fine
- if he prints to PDF, he doesn't get an option for "best for electronic distribution" (hence, the hyperlinks are not active in the TOC)

Any suggestions appreciated on possible solutions.
Thanks!
