Xamarin.Forms Label TextColor Not Applying

Question

I am experiencing an issue with setting the TextColor property for a Xamarin.Forms Label. Despite specifying a color, the text remains transparent. I have tried the following:

Ensured there are no conflicting parent styles affecting the Label. Checked for platform-specific styles for iOS, Android, and UWP. Verified that there are no dynamic resource issues. Here's a simplified version of my XAML:

<ScrollView x:Name="scroller" Orientation="Horizontal" Padding="10,0">
 <StackLayout Orientation="Horizontal">
   <Label x:Name="label3" TextColor="White" FontSize="30"></Label>
     <Label x:Name="button2" TextColor="Black" Text="   " FontSize="30"></Label>

It's the same for BackgroundColor
