I changed to using subfigure inside figure. Now when I include more than 13 figures in one document, tex4ht gives
! LaTeX Error: Counter too large.
Same document compiles OK with lualatex. I made MWE below to show this. I am using TL 2022
\documentclass[12pt,titlepage]{article}
\errorcontextlines=500
\usepackage{graphicx}
\usepackage{subcaption}
\usepackage{forloop}
\newcommand{\R}{\begin{figure}
\centering
\begin{subfigure}{0.45\textwidth}
\centering
\includegraphics[width=\textwidth]{example-image-a}
\caption{Solution plot}
\end{subfigure}%
\begin{subfigure}{0.45\textwidth}
\centering
\includegraphics[width=\textwidth]{example-image-b}
\caption{Phase plot}
\end{subfigure}%
\end{figure}}
\begin{document}
%13 figures OK. 14 figure fails
\newcounter{x}
\forloop{x}{1}{\value{x} < 15}{%change this to 14 it works

Command used is

Since I need to include 1,000's of figures, this limitation will not work for me. I think the problem started when I changed to using \begin{subfigure}. It seems there is limitation of number of subfigures in tex4ht in one document? I need to see if I can find a workaround.
The question is: Why does the above fail in tex4ht and not in lualatex/pdf?
ps. I am using the same setup as shown in htlatex-and-subfigures in order to have side-by-side subfigures. This was from 2015. It works OK now in TL 2022 as is, but it fails when more than 13 figures are loaded.
