我们有一个 C# .Net Framework Windows 窗体应用程序，它引用了几个 c/c++ 本机 DLL，正在由少数客户端测试。
在某些机器上，它崩溃而没有任何错误消息/弹出（只是立即退出），这只发生并且总是在因此选择的机器上（应用程序崩溃的所有电脑和应用程序从未出现问题的电脑都有最新的Windows 10 版本，并且都禁用了 Windows Defender/Security，因为它会导致问题）。
应用程序在启动 http 请求后恰好崩溃/退出，因此此时它会加载System.Net.Http包含在主可执行文件中的 .Net Framework 的库（不知道为什么 VS 包含了我们在应用程序中使用的几乎所有标准库）。
无论如何，在使用 WinDBG 调试应用程序后，日志显示当启动 http 请求时，应用程序加载了这个加载本机 dll 的 dll“System.Net.Http.ni.dll”，这SysWOW64\WINNSI.DLL就是它的fast_fail()来源，它似乎是从要么 要么System.Net.Http.ni.dll，SysWOW64\WINNSI.DLL确切的子代码是0x2 FAST_FAIL_STACK_COOKIE_CHECK_FAILURE。
我们一直认为可能是依赖冲突引起的，解决了所有的冲突后仍然发生崩溃，此时我们不知道在哪里寻找原因。
一些信息：
- 主 App/EXE 使用 .Net Framework v4.6.2
- 使用 .Net Framework 4.6 引用其他一些项目
- 该应用程序以发布模式部署并且被混淆（包括打包器/压缩器）
任何帮助/信息将不胜感激，WinDBG 的日志包含在下面。
