C# IIS Express:System.ComponentModel.Win32异常：访问被拒绝

我刚刚从VS 2015升级到VS 2019。我创建了一个标准MVC项目，执行后，这个错误出现在标准500错误页面中的“System.ComponentModel.Win32Exception:访问被拒绝”

我没有更改标准项目的默认microsoft代码中的任何内容。 试图以管理员身份执行VS，但没有任何更改

我知道有很多人都有这个问题，但他们都在谈论生产中的问题，当我在Visual Studio的调试中启动应用程序时，这种情况就会发生

VS和IIS Express的进程由具有管理员权限的用户拥有

提前谢谢你的帮助

完全错误：（“Accesso negato”是意大利语，表示“拒绝访问”）
