The property 'Content' is set more than once - XAML

Every time i try to implement <maps:Map IsShowingUser="True" x:Name="Mapa" /> in my mainPage show's "The property 'Content' is set more than once". Every time I put in this place gives me 'The property 'Content' is set more than once'.

If anyone could explain in simple terms where the Content property is set that would be most helpful.

<ContentPage xmlns:maps="clr-namespace:Xamarin.Forms.GoogleMaps;assembly=Xamarin.Forms.GoogleMaps"
             xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:d="http://xamarin.com/schemas/2014/forms/design"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             mc:Ignorable="d" 
             x:Class="Pap.MainPage">

    <maps:Map IsShowingUser="True" x:Name="Mapa" />

    <AbsoluteLayout VerticalOptions="FillAndExpand" x:Name="Main">
        
        <StackLayout AbsoluteLayout.LayoutBounds="0,0,1,1" AbsoluteLayout.LayoutFlags="All" x:Name="main" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand">
            <Image Source="C:\Users\david\Desktop\Pap\Pap\Pap.Android\Resources\drawable\User.png" Aspect="AspectFill" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand"></Image>

        </StackLayout>
        <StackLayout x:Name="body" AbsoluteLayout.LayoutBounds="0,0,1,1" AbsoluteLayout.LayoutFlags="All"
   Orientation="Vertical" VerticalOptions="FillAndExpand" Spacing="0">
            <!--<StackLayout VerticalOptions="End" BackgroundColor="Red">
    <Label Text="Titulo" />
    
   </StackLayout>-->
            <StackLayout VerticalOptions="FillAndExpand">
                <Label Text="Slider-Example"  HorizontalOptions="Center" VerticalOptions="Center"/>
                <Image Source="C:\Users\david\Desktop\Pap\Pap\Pap.Android\Resources\drawable\User.png" Aspect="AspectFill"></Image>
                <StackLayout.GestureRecognizers>
                    <TapGestureRecognizer Tapped="Handle_Tapped">
                    </TapGestureRecognizer>
                </StackLayout.GestureRecognizers>
            </StackLayout>
        </StackLayout>
    </AbsoluteLayout>

</ContentPage>

ContentPage has an implicit Content property that can contain a single child element. If you want to include more than one piece of content on your page, you need to use a Layout container, like a StackLayout

<ContentPage ... >
  <StackLayout>
    ... multiple children can go here
  </StackLayout>
</ContentPage>

if you were using C# instead of XAML, you would explicitly set the Content property

myPage.Content = new StackLayout{ ... };
