我正在尝试在新电脑上全新安装 MiKTex 和 TeXstudio 来编译一些 tex 文档。我的文件在其他电脑上编译没有问题。但当我尝试在这里编译它们时，它们会产生一个神秘的错误。控制台只是显示
抱歉，pdflatex.exe 未能成功。希望日志文件包含让 MiKTeX 再次运行的信息：C:\Users\ajaym\AppData\Local\MiKTeX\miktex\log\pdflatex.log
当我查阅日志文件时，我发现了下面的摘录。我对 pdflatex 的内部工作原理并不特别了解。似乎错误是在“Libraries\MiKTeX\TeXAndFriends\include\miktex/C4P/C4P.h:255”中生成的，但消息本身对解决问题没有多大帮助。
我不得不假设问题出在我的系统或我的 MiKTex 安装上（正如我所说，这些文件在我的另一台计算机上编译没有问题）。但我尝试重新安装 MiKTex 和 TeXstudio（安装程序建议的私人安装而不是管理员安装）。我正在运行最新版本的 Windows 10（成功编译文件的计算机也是如此）。说实话，我不知道从哪里开始。我所有的谷歌搜索都没有结果。
感谢您提供的任何帮助——Ajay Shenoy
