"Save copy as ... docx" results in "Unknown error." when 111 or more pages

Browser version: Firefox 111.0

We have a quite long docx-file. 321KB / 126 pages. When trying to create a copy via “File” → “Save copy as” → “DOCX” a small windows with the message “Unknown error.” occurs. I tested the same function with another, very small file and it works without any problem. To test it any further i created a new file, only Lorem Ipsum text, no formating. It works fine until 110 pages. With the 111th page the “Unknown error.” starts to happen.

Is this something that can be fixed or get an proper error message?

Thanks a lot!
