Could you please paste a XAML reproducing the issue?

The following xaml reproduces the issue when passing it to Noesis.GUI.ParseXaml:
<UserControl xmlns=http://schemas.microsoft.com/winfx/2006/xaml/presentation xmlns:x=http://schemas.microsoft.com/winfx/2006/xaml>
<UserControl.Resources>
<Style TargetType="Button" BasedOn="{StaticResource {x:Type Button}}">
<Setter Property="Content" Value="Submit" /></Style>
</UserControl.Resources>
<Grid>
<Button Width="100" Height="25"/>
<TextBlock Text="1-piece 135° duct" />
</Grid>
</UserControl>

Hi, if I load that attached xaml it complains about invalid token, because the xmlns definitions are missing the quotes.
If I fix that, then the xaml loads as expected. Perhaps the xaml was saved with a different encoding, could you please attach the file itself, not the xaml code?

I'm sorry about the missing quotes, the xaml I am using to reproduce the issue contains the quotes and is still not rendering both the button and the TextBlock. I can see the "Invalid Token" error in the Output. I am attaching a simple project that reproduces the issue.
Thank you.
