Powershell 'runspace' does not run from the Powershell console

I am trying to understand why this code will run in the Powershell ISE but not from the Powershell console

function close-window (){
    # close
    $hash.window.Dispatcher.Invoke("Normal",[action]{ $hash.window.close() })
    # clean up
    $powershell.EndInvoke($handle) | Out-Null
    $runspace.Close() | Out-Null
    $powershell.Dispose() | Out-Null
}

    $hash = [hashtable]::Synchronized(@{})
    $runspace = [runspacefactory]::CreateRunspace()
    $runspace.ApartmentState = "STA"
    $Runspace.ThreadOptions = "ReuseThread"
    $runspace.Open()
    $runspace.SessionStateProxy.SetVariable("hash",$hash)
    $Powershell = [PowerShell]::Create()
    $powershell.AddScript({ 
    $xaml = [xml]@"
        <Window
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        x:Name="Window" Title="Splash Screen" WindowStyle="None" WindowStartupLocation="CenterScreen"
        Width="499" Height="272" BorderBrush="#FF2AA0F1" ShowInTaskbar = "False" AllowsTransparency="True"
        ResizeMode = "NoResize" BorderThickness="1" >
    </Window>
"@

    $reader = New-Object System.Xml.XmlNodeReader $xaml
    $hash.window = [Windows.Markup.XamlReader]::Load($reader)
    $hash.window.Add_MouseRightButtonUp({ $hash.window.close() })
    $hash.window.ShowDialog()
})

    $Powershell.Runspace = $runspace
    $handle = $Powershell.BeginInvoke()

Run it from the ISE and you get the expected result of a XAML window appearing. Save the file and run it from the console and it fails silently Copy and paste it into the console and it fails silently.

It contains a single runspace with a synchronised hashtable Because it is XAML, I start the runspace as a single threaded apartment. When running from the console have tried MTA and STA

The aim is to use this piece of code as part of a splash screen.

The script was missing references to any assembly names, not a problem in the ISE but required for the console.

 Add-Type -AssemblyName PresentationCore, PresentationFramework
