Access violation in generated code when reading 0xffffffffffffffff

[unitscan]

Reading the various answers on this site, I tried a way to convert a .tex file containing images generated with tikz into an editable format with MS Word. I followed the various instructions exactly, but the command prompt gives me this error:

Access violation in generated code when reading 0xffffffffffffffff

I used this comand line: pandoc --from latex+raw_tex --lua-filter=tikz.lua -s test.tex -o test.docx

The tex code is as follows

\documentclass{article} 
\usepackage{amsmath,tcolorbox,tikz}

\begin{document}

\begin{tcolorbox}[colback=red!5!white,colframe=red!75!black]
  Some content and an equation $a=b$
\end{tcolorbox}

\begin{center}
\begin{tikzpicture}
\draw (0,0) -- (4,4);
\end{tikzpicture} 
\end{center} 

\end{document}

The Lua script is https://gist.github.com/gfacciol/4099a3e28a2a29611d1d3323071f7be0

The same command without Lua script works. Of course, only text on the outpit file.

Pandoc version: 3.1.13
OS: Windows 10

I suspect this has to do with that Lua script (which obviously wasn't written with Windows in mind - note the \n line endings).

I don't think it is an issue in pandoc itself, and I can't diagnose further because I don't have a Windows box. I'll convert this to a Discussion item; maybe someone will have advice.
