latexdiff PDF 文件无法编译

我正在尝试使用 比较两个 TeX 文件latexdiff。我已经完成了所有必要的步骤，我正在比较的两个 TeX 文件都是有效的，并且编译没有任何问题，当我运行时会生成latexdiff一个cmd.exe新文件。diff.tex

但是，当我尝试diff.tex在 TeXstudio 中编译该文件以获取 PDF 时，PDF 并未生成，我只收到一个带有错误的长日志文件，开头如下：

This is pdfTeX, Version 3.141592653-2.6-1.40.23 (MiKTeX 21.8) (preloaded format=pdflatex 2021.9.29)  28 JAN 2023 11:31

The control sequence at the end of the top line

misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

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

如果您能提供任何关于如何解决此问题的建议，我们将不胜感激。谢谢。

编辑：如果有帮助的话：我也尝试使用两个带有最少 LaTeX 代码的非常基本的文档来运行相同的过程，但遇到了相同的错误。

我遇到了类似的问题，diff.tex每个字符之间都有空格，因此我无法编译。

当我使用 XeLaTeX 或 LuaLaTeX（而不是 pdfLaTeX）进行编译时，这似乎解决了这个问题，并且我能够毫无问题地进行编译。
