I've been working with Writer for quite some time now, trusting the system to build up a document (a ttrpg project) of hundreds of pages. This document is filled to the brim with markers and related sections plus some images.

Yesterday I could export to PDF no problem but now it freezes every single time I try it, keeping the lock files for the odt and the pdf file it's supposed to be creating, plus the tmp file. I tried deleting these from the base folder and opening the file again with no luck for the exporting process, and I noticed a very concerning reduction in page number (from 152 to 149), but I cannot seem to locate the loss of content.

I'm working from a Windows 10 with the latest version of Writer (7.6.0.3) using X86_64. Does someone else here save the same problem or know for an easy solution? If not, is there an alternative or a way to convert the odt file into something MS Word can easily interpret?
