I'm having trouble opening my projects in Visual Studio. I get the following error and the project does not load.

Creation of virtual directory failed with the following error: Filename: C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\web.config

Line number: 24

Error: The configuration section 'fulltrustassemblies' cannot be read because it is missing a section declaration.

my application is configured to use local IIS

I tried creating a new ASP.NET webform application with target framework 4.7.2 (same as the ones of the project that does not load) and get the same issue. Any help is appreciated.

Thanks
