当我尝试编译这个 mwe 时，XeLaTeX 给出了一些我不明白的奇怪错误消息。它仍然会为这个 MWE 编译 PDF，但它的开头有一个带空格的“<”——在其他文件中，它给出了同样的错误，但甚至没有创建 PDF。即使使用 MWE，它也会很多编译时间。我已经有一段时间没用过 Latex 了，但今天之前一切都正常，不知道发生了什么变化。我重新安装了所有东西，试图修复所有出错的地方。
我在 Windows 10 下使用 Texmaker 5.1.2。我使用在 Texmaker 配置菜单中配置的属性“xelatex -synctex=1 -interaction=nonstopmode %.tex”运行 XeLaTeX。
梅威瑟：
\documentclass[12pt]{article}
\begin{document}
\section{Test}
Test
\end{document}
我已经尝试过的东西：
- 完全卸载 MiKTeX，重新安装最新版本，运行控制台，更新所有内容
- 安装了最新版本的 TexMaker
- MiKTeX 设置为一个用户。（之前也设置过这个
- 将 Biber 更新到最新版本（我不知道这是否与错误有关），我切换回旧版本，仍然是同样的错误。

l.80 ...c__kernel_sys_dvipdfmx_version_int { 0 } }
I've run across a `}' that doesn't seem to match anything.
For example, `\def\a#1{...}' and `\a}' would produce
this error. If you simply proceed now, the `\par' that
I've just inserted will cause me to report a runaway
argument that might be the root of the problem. But if
your `}' was spurious, just type `2' and it will go away.
Runaway argument?

\par
l.80 ...c__kernel_sys_dvipdfmx_version_int { 0 } }
I suspect you've forgotten a `}', causing me to apply this
control sequence to too much text. How can we recover?
My plan is to forget the whole thing and hope for the best.

\scan_stop:
l.80 ...c__kernel_sys_dvipdfmx_version_int { 0 } }
A number should have been here; I inserted `0'.
(If you can't figure out why I needed to see a number,
look up `weird error' in the index to The TeXbook.)
! Missing = inserted for \ifnum.

\tex_par:D

I was expecting to see `<', `=', or `>'. Didn't.

Type H <return> for immediate help.

You're in trouble here. Try typing <return> to proceed.
If that doesn't work, type X <return> to quit.

Sorry, but I'm not programmed to handle this case;
I'll just pretend that you didn't ask for it.
If you're in the wrong mode, you might be able to
return to the right one by typing `I}' or `I$' or `I\par'.
