After changing the command and adding "mathml", now some
of my latex files no longer compile.

Please see this MWE

\documentclass{article}
\usepackage{amsmath}
\begin{document}
$n^\text{th}$
\end{document}

THe above used to compile OK using

          make4ht filename.tex "mathjax,htm"

But now using

          make4ht filename.tex "mathml,mathjax,htm"

it gives error

(base) >make4ht foo4.tex "mathml,htm,mathjax"
[STATUS]  make4ht: Conversion started

I am using TL 2020. Just updated fully now.

(base) >make4ht --version
