SphereCommunity

I have cloned sphere source git and builded with success using visual studio 2015 but when I try to debug I get the exception:
Unhandled exception at 0x7779DDC2 in SphereSvr.exe: Microsoft C++ exception: CGrayAssert at memory location 0x001FF75C.

The exception is thrown because in class CWindow the method IsWindow is returning false

BOOL IsWindow() const
{
if ( this == NULL )
return( false );
if ( m_hWnd == NULL ) <---- IT IS NULL
return( false );
return( ::IsWindow( m_hWnd ));
}

Downloaded visual studio 2017 like it is in the readme (selecting the requirements during the installation) but it made no diference.

I am trying to build targetting x86, Windows sdk version: 10.0.17134.0

If I ignore this exception and continue, the console open and load all scripts but then start to give these errors until it get to this line _DEBUG_ERROR("map/set iterator not dereferencable"); and the crash.
