IIS Express: System.ComponentModel.Win32Exception: Access is denied

I just upgraded from VS 2015 to VS 2019. I create a standard MVC project, execute and this error appears "System.ComponentModel.Win32Exception: Access is denied" in the standard 500 error page.

I didn't change anything in the default microsoft code of the standard project. Tried to execute VS as administrator but nothing changes.

I know there are a lot of people with this problem but they are all talking about problems in production, this happens to me when I start the app in debug from Visual Studio.

The processes of VS and IIS Express are owned by my user with administrator privileges.

Thanks in advance for the help.
