我到处寻找答案。我尝试thesis.tex在 texstudio 中编译我的文件（使用 miktex）。一切正常，没有出现任何错误，直到我尝试添加，\usepackage{tikz}然后出现以下错误，并不断出现。它说这些错误在 .toc .lot 和 .lof 文件中，但我找不到其中的任何错误。
我还应该指出，在我妻子的电脑上，同样的代码在同样的设置下也能正常工作。她根本没有遇到这些错误。我们都在使用 Windows 10。

我尝试删除整个代码并重新开始，并删除 .toc .lof 和 .lot 文件。我尝试卸载 texstudio（通过控制面板和 texstudio 的卸载选项）和 miktex 并重新安装，我尝试重新配置 texstudio。我完全不知所措，已经为此困扰了好几天。
