This document doesn't typeset for me because my TeX Live 2023 doesn't
have "template" class. After I replaced
\documentclass{template}
with
\documentclass{article}
, I can both typeset and use preview-latex for the files quoted below.
Hence I suppose that the issue isn't related directly to \newcommand and
suspect there is something incompatible with preview-latex in
the non-standard class file template.cls.

--- foo.tex ----------------------------------------------------------
\documentclass{article}
\title{Some title}
\author{XXX}
\begin{document}
\maketitle

\include{symbols}

From classical Boltzmann statistics we know that the probability for finding any
particle in a given state $i$ is,
\[ \frac{N_i}{N} = \frac{\exp \left( - E_i / \kb T \right)}{Z\kb \d } \]

\end{document}
----------------------------------------------------------------------

--- symbols.tex ------------------------------------------------------
\newcommand{\kb}{k_{\mathrm{B}}}
\renewcommand{\d}{\mathrm{d}}

%%% Local Variables:
%%% mode: LaTeX
%%% TeX-master: "foo"
%%% End:
