I can't figure what the problem is. But it has to do with
some file(s) in the  folder itself.  I get the error on
this MWE

===========================
\documentclass[11pt,notitlepage]{report}%
\begin{document}
test
\end{document}
==============================

WHich makes no sense.  Using the command

make4ht -ulm default -c ./nma_mathjax.cfg index.tex
    "htm,0,mathjax,notoc*,p-width,charset=utf-8" " -cunihtf -utf8"

It gives

====================================

If I remove random files from the same folder my index.tex is in,
which is not related at all, the error can go away.

I am running this on ubuntu under windows 10 subsystem.

I need to try this again Linux under virtual machine. But need more
time.

May be it is windows 10 linux subsystem is doing some tricks.

Could someome please try this?  I put the folder itself which
contains index.tex and my current nma_mathjax.cfg in it.

All what you have to do is download the zip file, unzip it and
cd to the folder strange_error/ it creates and just type the
command I show above.

Here is the zip file, it is in this folder

https://www.12000.org/tmp/012119/

Again, the error goes away when I delete some unrelated files from the
folder itself. I kept them all in there for now, since I could not
find out which specific file(s) causing this. And I have no idea why this
happens as all the other files are not related to index.tex at all.

Thanks
