更新 2022 年 2 月 27 日：问题已得到解答。请参阅下面的评论。感谢大家的帮助。
和这里很多人遇到的问题一样。几个月没用过后，我启动了 LaTex 项目，结果……它不再工作了。LaTex 就是这么让人恼火。
无论如何，已经过去了几天，我还是无法找出这个该死的Extra \endgroup. \begin{document}错误来自哪里。我已将\listfiles日志粘贴在下面。

答案1
该软件包xwatermark与后者属于同一作者，catoptions并且建立在后者软件包之上。
不幸的是，尽管有人反复建议对内核命令进行低级更改并不是好策略，因为 LaTeX 的新版本可能会破坏这些更改，但作者还是忽略了这一建议。
LaTeX 内核的最新更新确实破坏了catoptions。使用它的软件包不再起作用。不要使用它们。
