Sudden conflict memoir and hyperref

[Lars Madsen]

Just for reference the correct fix (by David) is


 \newcommand\AtEndPackage[2]{\def\temp{\AddToHook{package/after/#1}{#2}}\temp}

so as a temp fix add

\renewcommand\AtEndPackage[2]{\def\temp{\AddToHook{package/after/#1}{#2}}\temp}

before loading hyperref

An updated memoir has been sent to CTAN

Subject: Re: Sudden conflict memoir and hyperref

Memoir switched to use the new hook code but the old version required doubling the # the new one not.
A quick fix would be to add

\let\OldAtEndPackage\AtEndPackage
\def\AtEndPackage#1{\def\temp{#1}\expandafter\OldAtEndPackage\expandafter{\temp}}

but that would break if the code was updated, Possibly best would be to make a local copy of memhfixc.sty and replace ## by #
but we'll coordinate with Lars (CC'ed) and get an update to ctan

After tonight update of TL-2020 there is a conflict between memoir and hyperref.


\documentclass[12pt]{memoir}

\usepackage{hyperref}

\begin{document}

Hello, World

\end{document}

Replacing memoir with article or switching off hyperref resolves it

Note that neither hyperref nor memoir were updated, but latex was
