Undefined control sequence when using algorithm environment with dgruyter.sty

Question

I need to write a document using the dgruyter template. When I include an algorithm environment I get the following error.

Undefined control sequence.
<write> ...\protect \numberline {\plist@algorithm 
                                                  1}{\ignorespaces Alg\relax... l.32 \end{document}
                    The control sequence at the end of the top line of your error message was never \def'ed. If you have misspelled it (e.g.,
\hobx'), typeI' and the correct spelling (e.g., `I\hbox').
Otherwise just continue, and I'll forget about whatever was undefined.

MWE:

\documentclass[USenglish]{article}
\usepackage[big,online]{dgruyter}
\usepackage{algorithm,algpseudocode}
\begin{document}
\begin{algorithm}[t]
\caption{Alg}
\begin{algorithmic}[1]
    \State Test
\end{algorithmic}
\end{algorithm}
\end{document}

Sigh, you should moan to the publishers, they should fix this

https://cs.uwaterloo.ca/twiki/view/CrySP/LaTeXSnippets

discusses several errors in this file including this one.

This works

\documentclass[USenglish]{article}
\usepackage[big,online]{dgruyter}
\usepackage{algorithm,algpseudocode}
\makeatletter
\def\plist@algorithm{Alg.\space}
\makeatother
\begin{document}
\begin{algorithm}[t]
\caption{Alg}
\begin{algorithmic}[1]
    \State Test
\end{algorithmic}
\end{algorithm}
\end{document}

The package still has \p@=1bp\relax after all these years and multiple reports so it basically breaks latex arithmetic. – David Carlisle Sep 24 '23 at 20:49

I once complained about that. Answer: "Most LaTeX experts say that's OK." – campa Sep 24 '23 at 20:52

I have complained more than once and I didn't say it was OK:-) @campa – David Carlisle Sep 24 '23 at 20:54
It seems not OK if it breaks a basic package :'( I'll try to find out where to file a bug report. And thank you very much! – Alex bGoode Sep 24 '23 at 20:59
@AlexbGoode the 1bp thing isn't the cause of this error, but it does break \includegraphics, tabularx, .... – David Carlisle Sep 24 '23 at 22:43
