I feel like Tridion DLL and Provider DLL versions are not in sink.

There is some mismatch with version, which cause this issue.

Update:

Try moving DependencyInjectionConfig.Configure(); to end of Application_Start()

protected void Application_Start() 
{
        AreaRegistration.RegisterAllAreas();

        WebApiConfig.Register(GlobalConfiguration.Configuration);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);

        DependencyInjectionConfig.Configure();
}
