Error when using DraggableViewCell into CollectionView

[AmirImam]

H
I have an error that appears when I try to display a DraggableViewCell into a CollectionView
The error is:
Attempt to invoke virtual method 'android.view.ViewGroup$LayoutParams android.view.View.getLayoutParams()' on a null object reference

Sharpnado.CollectionView 2.1.0
Xamarin.Forms 5.0.0.2515

Xaml Code:

<StackLayout>
        <sho:CollectionView
            x:Name="Collector"
            EnableDragAndDrop="True"
            ItemHeight="140"
            ItemSpacing="20"
            ItemsSource="{Binding DesiresList}"
            VerticalOptions="FillAndExpand">
            <sho:CollectionView.ItemTemplate>
                <DataTemplate>
                    <sho:DraggableViewCell IsDragAndDropping="True" IsDraggable="True">
                        <ContentView>
                            <StackLayout>
                                <Label Text="{Binding Name}" />
                            </StackLayout>
                        </ContentView>
                    </sho:DraggableViewCell>

                </DataTemplate>
            </sho:CollectionView.ItemTemplate>
        </sho:CollectionView>
    </StackLayout>

Note:
The library works fine when I create a new empty project, but this error appeared when I try to run it on the existing project, and
There are a lot of libraries that already installed on this project.

Update:
This error appearing now
Cannot invalidate item decorations during a scroll or layout
Nothing changed, just this error appeared instead of the previous one
