Xamarin MAUI application not shows correct output

Question

I have downloaded Visual Studio 2022 Professional (preview) version from MS Document. Also I have followed the other steps to create first sample application using .Net MAUI template after VS installed.

It does create new project with all the required dependency. I have installed Android sdk api v30 and created a simulator as mentioned in the official document.

When I have run the application on Android Emulator it does take a lot time to run and after it loaded properly it shows wrong output. It's just showing two Hello World label, while MainPage.xaml does have button as well but that button is not displayed. I have attached output screenshot here:

MainPage.xaml

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="MauiApp1.MainPage">

    <ScrollView>
        <VerticalStackLayout Spacing="25" Padding="30">

            <Label 
                Text="Hello, World!"
                SemanticProperties.HeadingLevel="Level1"
                FontSize="32"
                HorizontalOptions="Center" />

            <Label 
                Text="Welcome to .NET Multi-platform App UI"
                SemanticProperties.HeadingLevel="Level1"
                SemanticProperties.Description="Welcome to dot net Multi platform App U I"
                FontSize="18"
                HorizontalOptions="Center" />

            <Label 
                Text="Current count: 0"
                FontSize="18"
                FontAttributes="Bold"
                x:Name="CounterLabel"
                HorizontalOptions="Center" />

            <Button 
                Text="Click me"
                FontAttributes="Bold"
                SemanticProperties.Hint="Counts the number of times you click"
                Clicked="OnCounterClicked"
                HorizontalOptions="Center" 
                BackgroundColor="Orange" TextColor="White"/>

            <Image
                Source="dotnet_bot.png"
                SemanticProperties.Description="Cute dot net bot waving hi to you!"
                WidthRequest="250"
                HeightRequest="310"
                HorizontalOptions="Center" />

        </VerticalStackLayout>
    </ScrollView>
</ContentPage>

Does anyone know what is wrong here in the app? I have followed the steps mentioned in the MS Document which I have mentioned in the question.
