TextBox shows "System.Windows.Controls.TextBox" when opening PS1 file via .lnk - wpf

Question

I made a small application in WPF and powershell using XML for the gui template.
The whole application works fine when i open it with right-mouse click and open with powershell of even when i open it true a .exe file that i made for it.
But when i try to open it with a .lnk file it does not show its velue's but instead it presents me with "System.Windows.Controls.TextBox".
I can not show all of my code due to security reasons but i can on collaborate when needed.
P.s I don't often post on stack overflow, if i did something wrong please let me know.
In the XML:
[xml]$04Instellingen = #"

Code powershell:

Where it gets its velue's from:
