Can't get this to run my own hello world.

[Tuxhedoh]

using namespace Terminal.Gui

Add-Type -path $PSScriptRoot\NStack\netstandard2.0\NStack.dll
Add-Type -Path $PSScriptRoot\Terminal.Gui\netstandard2.1\Terminal.Gui.dll


function verb-noun {
    [cmdletbinding()]
    [Alias('vn')]
    param()

    [Application]::Init()
    [Application]::QuitKey = 'Esc'

  $window = [Window]@{
        Title = "My Window Title"
  }

  $lblHello = [Label]@{
        #X and Y are relative positions in the window
        X    = 1
        Y    = 1
        Text = 'Hello World'
    }

  window.Add($lblHello)

  }

When I run this... I get
Line | 4 | Add-Type -Path $PSScriptRoot\Terminal.Gui\netstandard2.1\Terminal.Gui … | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | Could not load file or assembly 'Terminal.Gui, Version=1.0.0.0, Culture=neutral, | PublicKeyToken=e2bd4b710393a695'. Assembly with same name is already loaded

When I comment out the Terminal.Gui command... it just "runs" and returns me back to the command line.

Thoughts?
