Not able to load main document with latest version of libreoffice (version 7.6.4)

After I upgraded my laptop from Ubuntu 22.04 which had libreoffice version 7.3.7 to Ubuntu 23.10 which has libreoffice version 7.6.4, I am no longer able to open the main.fodt document with libreoffice. It just freezes or takes forever to load. The same happens if I try to open the old main document OPM_Flow_Reference_Manual.fodt in the root of this repository.

I can open the sub documents like 4.fodt fine.

I can think of two things that are common for the two main documents: They both include the font descriptions, and they are both large documents. Hopefully the fonts are the problem for this should be easier to fix.

FYI Works with Debian stable and version 7.4 on my machine.

Tried to remove the font descriptions from main.fodt using a Python script. Unfortunately it did not help. So it seems the issue is not related to the fonts then.

I compiled a debug version of libreoffice development version and was able to get a backtrace for opening OPM_Flow_Reference_Manual.fodt. After waiting approximately 10 minutes, I attached gdb to the running libreoffice process and got this backtrace: gdb.txt. Not able to infer much about the problem by looking at backtrace though..

@blattms Great! It also works with version 7.5 in a docker container with Ubuntu 22.04, see #96.

FWIW I am able to open main.fodt with LibreOffice 7.5.9.2 (X86_64) on Windows 11. (LibreOffice 7.6.4 seemed less stable than 7.5.9 on my machine)

After I rebuilt the docker image, I am no longer able to open main.fodt even within the docker container

On my linux machine (Debian 12) it works (with #214).
On Windows I have problems, though
