Playing music in Powershell stops when assigned to button - wpf

Question

I'm facing a problem that I cannot get solved or understand with playing music from Powershell, I made a WPF GUI on top of my Powershell script.
It all works perfect except that when I press the play music button I made the music starts but after a few seconds stops.
Or when moving the mouse over the WPF GUI the music stops and I cannot get it solved. When I throw the code for playing the music in the project it works flawless, only when I assign a button to it the problems start.
So I made a stripped down version with a simple old form and a button nothing more, made an add_Click event to connect the button the code and tested again. Same problem again music stops playing either after a few seconds or when you move your mouse over the form.
Now I still had an old Windows 7 machine hanging around with Powershell V2 still on it, and guess what it worked flawlessly! Then I upgraded Powershell v2 to V5 on that machine and I had the same problem as on Win 10 (1909 with PS 5.1) laptop, so something changed with Powershell between V2 and V2 that causes this behavior, but I cannot find what.
Some examples, when I throw these lines of code in the project it works:
Add-Type -AssemblyName presentationcore
$location = (C:\users\myuserid\test.mp3)
$PlaySound = New-Object System.Windows.Media.MediaPlayer
$PlaySound.open($location)
$PlaySound.Play()
But as soon as I assign a button to it the problem as described above appears
So stripped all down to bare bones to rule out as much as I can:
Add-Type -AssemblyName System.Windows.Forms
Add-Type -AssemblyName System.Drawing
Add-Type -AssemblyName presentationcore
# Build Form
$Form = New-Object System.Windows.Forms.Form
$Form.Text = "My Form"
$Form.Size = New-Object System.Drawing.Size(200,200)
$Form.StartPosition = "CenterScreen"
$Form.Topmost = $True
# Add Button
$Button = New-Object System.Windows.Forms.Button
$Button.Location = New-Object System.Drawing.Size(35,35)
$Button.Size = New-Object System.Drawing.Size(120,23)
$Button.Text = "Play music"
$Form.Controls.Add($Button)
#Add Button event
$Button.Add_Click({
$location = 'D:\test\test.mp3'
$PlaySound = New-Object System.Windows.Media.MediaPlayer
$PlaySound.open($location)
$PlaySound.Play()
})
#Show the Form
$form.ShowDialog()| Out-Null
So when resizing the form when the music plays will cause it to stop 95% of the time. But when I throw the code in for playing the music without the button like this it never breaks.
Add-Type -AssemblyName System.Windows.Forms
Add-Type -AssemblyName System.Drawing
Add-Type -AssemblyName presentationcore
# Build Form
$Form = New-Object System.Windows.Forms.Form
$Form.Text = "My Form"
$Form.Size = New-Object System.Drawing.Size(200,200)
$Form.StartPosition = "CenterScreen"
$Form.Topmost = $True
# Add Button
$Button = New-Object System.Windows.Forms.Button
$Button.Location = New-Object System.Drawing.Size(35,35)
$Button.Size = New-Object System.Drawing.Size(120,23)
$Button.Text = "Play music"
$Form.Controls.Add($Button)
#Add Button event
$Button.Add_Click({
#Button now does nothing.. and music plays without breaking...ever
})
#Now it will always play to the end no matter what :-S
$location = 'D:\test\test.mp3'
$PlaySound = New-Object System.Windows.Media.MediaPlayer
$PlaySound.open($location)
$PlaySound.Play()
#Show the Form
$form.ShowDialog()| Out-Null

(Posted solution on behalf of the question author, to move it to the answer space).
I fixed the problem myself, the trick is to load the player at the beginning of your script like this:
#Clear the Console
CLS
#Determine Script location
$SCRIPT_PARENT = Split-Path -Parent $MyInvocation.MyCommand.Definition
#Add in the presentation core
Add-Type -AssemblyName presentationframework, presentationcore
#Load music player and set location here!
$location = ($SCRIPT_PARENT + "\Music.mp3")
$PlaySound = New-Object System.Windows.Media.MediaPlayer
###############################################################
# here comes a whole lot of code (XAML for WPF GUI etc etc) #
###############################################################
# Then in your event system only put:
#Play button action
$MainGUI.Playmusic.add_Click({
#Open file and play music
$PlaySound.open($location)
$PlaySound.Play()
})
This solved the playing problem 100%.
