Expected Behavior

the popup view appears.

Steps To Reproduce

Create a Style in the ResourceDictionary like this:

<Style TargetType="Border">
    <Setter Property="StrokeShape"
            Value="RoundRectangle 5" />
    <Setter Property="Stroke"
            Value="{AppThemeBinding Light={StaticResource LightCardBackgroundColor}, Dark={StaticResource DarkCardBackgroundColor}}" />
    <Setter Property="BackgroundColor"
            Value="{AppThemeBinding Light={StaticResource LightCardBackgroundColor}, Dark={StaticResource DarkCardBackgroundColor}}" />
</Style>

And create a popup control like this:

<?xml version="1.0" encoding="utf-8" ?>
<toolkit:Popup xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
       xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit"
       xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
                x:Class="MatoProductivity.Views.AppActionSettingPage"
                Opened="PopupBase_Opened"
                Size="200,200"
                Color="Transparent"
                x:Name="MainPage"
                VerticalOptions="End"
                HorizontalOptions="Fill">
    <Border></Border>

It's worth mentioning that when Stlye is not defined anonymously, The program runs normally

this is Ok:

    <Style TargetType="Border"  x:Key="FrameEntry">
        <Setter Property="StrokeShape"
                Value="RoundRectangle 5" />
        <Setter Property="Stroke"
                Value="{AppThemeBinding Light={StaticResource LightCardBackgroundColor}, Dark={StaticResource DarkCardBackgroundColor}}" />
        <Setter Property="BackgroundColor"
                Value="{AppThemeBinding Light={StaticResource LightCardBackgroundColor}, Dark={StaticResource DarkCardBackgroundColor}}" />
    </Style>

    <Border Style="{StaticResource FrameEntry}">

I defined and validated implicit styles in the ResourceDictionary in App.xaml and TestPopup.xaml.

The validation results when the style is defined in App.xaml are shown below. Since the github repository was not made public, I do not know how LightCard BackgroundColor and BackCare BackgroundColor were defined, but I defined them as follows.

[App.xaml]

<Application xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"

             x:Class="PopupTest.App">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Resources/Styles/Colors.xaml" />
                <ResourceDictionary Source="Resources/Styles/Styles.xaml" />
            </ResourceDictionary.MergedDictionaries>

            <Color x:Key="LightCardBackgroundColor">Blue</Color>
            <Color x:Key="DarkCardBackgroundColor">Red</Color>
            <Style TargetType="{x:Type Border}">
                <Setter Property="StrokeShape" Value="RoundRectangle 5" />
                <Setter Property="Stroke" Value="{AppThemeBinding Light={StaticResource LightCardBackgroundColor}, Dark={StaticResource DarkCardBackgroundColor}}" />
                <Setter Property="BackgroundColor" Value="{AppThemeBinding Light={StaticResource LightCardBackgroundColor}, Dark={StaticResource DarkCardBackgroundColor}}" />
            </Style>

The verification results when the style is defined in TestPopup.xaml are shown below.

                <Setter Property="BackgroundColor" Value="{AppThemeBinding Light={StaticResource LightCardBackgroundColor}, Dark={StaticResource DarkCardBackgroundColor}}" />
            </Style>
        </ResourceDictionary>
    </toolkit:Popup.Resources>
    <Border>
    </Border>
</toolkit:Popup>

https://github.com/CommunityToolkit/Maui/assets/125236133/be747f94-8afa-47f9-928e-6eef2d2c6d7e

No exceptions occurred in either case.

By the way, the theme at the time of verification was light.
