更新我的 Miktex 发行版（2023-07-03）后，我无法再编译我的代码。请参阅下面的 MNWE：
\documentclass{article}
% \usepackage{siunitx}
\usepackage{unicode-math} % sisetup uses \mitpi (require unicode-math)
\begin{document}
Hello world.
\end{document}
警告：
LaTeX hooks Warning: Generic hook 'package/before/amsmath' is deprecated.
(hooks) Use hook 'package/amsmath/before' instead.
! LaTeX Error: Control sequence \g__hook_package/amsmath/before_reversed_tl
(LaTeX) already defined.
我的另一个观察是，代码可以通过xelatex但不是（lualatex我的情况）。
该库中可能存在一个错误unicode-math，但不幸的是我没有足够的知识来修复它。

根据 samcarter_is_at_topanswers.xyz 的观察，问题似乎出在我的 Miktex 发行版中的旧包中（由于某种原因，它尚未自动更新）：
Package: lualatex-math 2021/07/05 v1.11 Patches for mathematics typesetting with LuaLaTeX
更新后
lualatex-math.sty 2022/01/01 v1.12 Patches for mathematics typesetting with LuaLaTeX
它运行正常。
