我已经安装了 Miktex 并对其进行了更新，尝试了这个示例：
\documentclass[]{article}
\begin{document}
hallow
\end{document}
我有这个错误：
This is XeTeX, Version 3.141592653-2.6-0.999994 (MiKTeX 22.10) (preloaded format=xelatex.fmt)
restricted \write18 enabled.
Sorry, but C:\...\AppData\Local\Programs\MiKTeX\miktex\bin\x64\miktex-xetex.exe did not succeed.
The log file hopefully contains the information to get MiKTeX going again:
C:\...\AppData\Local\MiKTeX\miktex\log\miktex-xetex.log
