我刚刚MikTeX从控制台更新。即使有以下 MWE（我猜在这种情况下是 MNWE）
\documentclass[a4paper,11pt]{article}
\begin{document}
I hate it here
\end{document}
我得到了错误
C:\Users\Usuario\Documents\test.tex:1: Extra \endcsname. []
C:\Users\Usuario\Documents\test.tex:1: Missing { inserted. []
C:\Users\Usuario\Documents\test.tex:1: Missing control sequence inserted. []
C:\Users\Usuario\Documents\test.tex:1: Extra \endcsname. []
C:\Users\Usuario\Documents\test.tex:1: Missing { inserted. []
说实话，这很烦人。简而言之，我无法编译任何事物和Lua更新后，一切都显示出这些错误。
上述 MNWE 的更完整日志如下：

A left brace was mandatory here, so I've put one in.
You might want to delete and/or insert some corrections
so that I will find a matching right brace soon.
If you're confused by all this, try typing `I}' now.

Please don't say `\def cs{...}', say `\def\cs{...}'.
I've inserted an inaccessible control sequence so that your
definition will be completed without mixing me up too badly.
You can recover graciously from this error, if you're
careful; see exercise 27.2 in The TeXbook.

我不知道“这里必须使用左括号”或诸如此类的东西是什么意思。
