java.lang.NoSuchMethodError when calling Navigation.PushPopupAsync()

[Kas-code]

Simplified example:

public partial class MyPage : ContentPage
{
        public MyPage()
        {
            InitializeComponent();
        }

        public async void PushPopup()
        {
            await Navigation.PushPopupAsync(new MyPopupPage());
        }
}

Upon calling Navigation.PushPopupAsync() the app crashes and we get this stack trace:

Fatal Exception: java.lang.NoSuchMethodError
    no non-static method "Landroid/view/WindowInsets;.getSystemGestureInsets()Landroid/graphics/Insets;"
    crc649782702a6ced2686.PopupPageRenderer.n_onLayout (PopupPageRenderer.java)
    crc649782702a6ced2686.PopupPageRenderer.onLayout (PopupPageRenderer.java:62)
    android.view.View.layout (View.java:20857)
    com.android.internal.os.ZygoteInit.main (ZygoteInit.java:1374) 

This is after an upgrade from Xamarin to MAUI.
The nuget package for RGPopup has been changed from the Xamarin one to this one.
We are calling .UseMauiRGPopup() on the builder in MauiProgram.cs
Popup pages throughout the app have been changed to inherit from RGPopup.Maui.Pages
All popups in the app throw this error.
Please advise.

This problem happens when accessing SystemGestureInsets here when running android with API version < 29.

Same problem here. The RGPopup sample also has this error.

Fixed by version 1.0.4 https://www.nuget.org/packages/RGPopup.Maui/1.0.4

Thanks very much for this issue reporting!
