Themed BusyIndicator crashes

I recently added a busy indicator on my main ChromelessWindow. 

It works fine with the default theme but whenever I try to use either MaterialLight or MaterialDark on my page, it crashes.


Using the latest version: 18.3.0.53

.NET Core: 3.1


Here's the XAML code:

<syncfusion:ChromelessWindow
    xmlns:busy="clr-namespace:Syncfusion.Windows.Controls.Notification;assembly=Syncfusion.SfBusyIndicator.WPF"
    xmlns:sfSkinManager="clr-namespace:Syncfusion.SfSkinManager;assembly=Syncfusion.SfSkinManager.WPF"
    x:Class="SimpleTrader.MainWindow"
    DataContext="{Binding MainWindowViewModel, Source={StaticResource ServiceLocator}}"
    sfSkinManager:SfSkinManager.VisualStyle="MaterialDark"
    Loaded="Window_Loaded">
    <busy:SfBusyIndicator
        AnimationType="Gear"
        Header="Authenticating"
        IsBusy="True">
        <Label>Test</Label>
    </budy:SfBusyIndicator>
</syncfusion:ChromelessWindow>
        

Here's the stack trace:
