以下是我认为与我的问题相关的内容（取自日志文件纺织机械商):................................................................
This is pdfTeX, Version 3.141592653-2.6-1.40.25 (MiKTeX 23.10.12) (preloaded format=pdflatex 2023.4.18) 27 NOV 2023 12:10

LaTeX2e <2022-11-01> patch level 1
L3 programming layer <2023-03-30>
(C:\Program Files\MiKTeX\tex/latex/l3backend\l3backend-pdftex.def
File: l3backend-pdftex.def 2023-11-09 L3 backend support: PDF output (pdfTeX)
! LaTeX Error: Mismatched LaTeX support files detected.
(LaTeX) Loading 'l3backend-pdftex.def' aborted!
(LaTeX)
(LaTeX) The L3 programming layer in the LaTeX format
(LaTeX) is dated 2023-03-30, but in your TeX tree the files require
(LaTeX) at least 2023-10-10.
For immediate help type H <return>.
...
l.44 }
The most likely causes are:
- A recent format generation failed;
- A stray format file in the user tree which needs to be removed or rebuilt;
- You are running a manually installed version of l3backend-pdftex.def
which is incompatible with the version in LaTeX.
LaTeX will abort loading the incompatible support files but this may lead to
later errors. Please ensure that your LaTeX format is correctly regenerated.

Frank Mittelbach 给出了一个应该有效的答案。但是，fmtutil我最新版本的 MiKTeX 中不再存在该功能。
我尝试了一下：
C:\Program Files\MiKTeX\miktex\bin\x64>l3build install --full
l3build：安全风险：以提升的权限运行错误：找不到配置 build.lua
