Latex Rendering Error Only for Some Note Types

For some of my note types, Latex seems to work fine.
E.g.,

[latex][
a^2 + b^9 = c^2
][/latex]

in a field renders as

Great!

For other of my note types, the same or similar input in a field gives this error:

myAnkiAll.sty is an old file from an old computer (which got destroyed in a house fire). The new computer was not a reinstall from a time machine backup (backup hard drive also lost in fire), it is a fresh install of everything. I can’t work out why Anki is trying to use this old style file? And why for only some note types? I’m not using any addons.

The Latex preamble, etc., in Options is unchanged from the default, i.e.:

\documentclass[12pt]{article}

\special{papersize=3in,5in}

\usepackage{amssymb,amsmath}

\pagestyle{empty}

\setlength{\parindent}{0in}

\begin{document}

and

\end{document}

Each note type has its own latex header/footer - my guess is you were looking at a different note type.
