Hi Nasser, thanks for the report. I've fixed this in TeX4ht sources, and posted an explanation to TeX.sx. In short, the problem was that \begin and \end as redefined were not robust commands. This should be fixed now.

his MWE compiles OK with lualatex but fails in tex4ht once hyperref is added.



\caption{Phase plot $y^{\prime \prime}\left(t \right)+9 y \left(t \right)-\left(\left\{\begin{array}{cc}
8 \sin \left(t \right) & 0<t <\pi

  1. & \pi <t

\end{array}\right.\right) = 0$}


And now

make4ht -ulm default -a debug foo.tex "mathjax,htm"

(./foo.aux) (/usr/local/texlive/2022/texmf-dist/tex/latex/base/ts1cmr.fd)
[1] [2]
l.9 --- TeX4ht warning --- File `"example-image-a.xbb"' not found ---
l.9 --- TeX4ht warning --- Cannot determine size of graphic in "example-image-a
.xbb" (no BoundingBox) ---
! Undefined control sequence.
<argument> \EndPicture

l.14 \end{array}\right.\right) = 0$}


Removing hyperref it compiles clean. (ps. I used test image above so it can compile as is).

Is there a workaround for this?
