MAUI Databinding with CommandParameter return null

Question

<Grid Grid.Row="3">
    <CollectionView x:Name="collectionView" ItemsSource="{Binding GarbageCollectionModels}">
        <CollectionView.ItemTemplate>
            <DataTemplate x:DataType="{x:Type model:GarbageCollectionModel}">
                <Grid>
                    <Button x:DataType="vm:ConfiguratorViewModel"
                                Command="{Binding Source={RelativeSource AncestorType={x:Type vm:ConfiguratorViewModel}}, Path=DeleteInstanceCommand}"
                                CommandParameter="{Binding .}"/>

                </Grid>
            </DataTemplate>
        </CollectionView.ItemTemplate>
    </CollectionView>
</Grid>

[RelayCommand]
private async void DeleteInstance(GarbageCollectionModel garbageCollection)
{
    SendTestText = JsonConvert.SerializeObject(garbageCollection);
}

Null will be returned after click the button. This only happens in Release mode and not in debug in Visual Studio 2022 prew. Everything is done on the android platform.
