@adleywd yes, there are plans to add VirtualizedUniformGrid to ItemsControl, but not in priority right now.

So after more debugging sessions, I still could not find the issue, nor replicate it in a smaller project, but It seems to related to be using a MenuFlyout to remove items. When I try to remove a command directly from the Flyout or even invoke the code from a code behind the flyout, the bug happens. If I remove the item from any other source, another window by referring to the same RemoveCommand or even using the code behind as below, it works as expected.
While debugging I checked that could be related to the RecyclePool in ItemTemplateWrapper.cs but I'm not sure since I did not dig that much into it.
<ItemsRepeater x:Name="FavoritesItemRepeater" ItemsSource="{Binding FavoritesShows}" >
<ItemsRepeater.Layout>
<UniformGridLayout ItemsJustification="Start"
ItemsStretch="Fill"
MaximumRowsOrColumns="4"
MinColumnSpacing="5"
MinRowSpacing="2"
MinItemHeight="120"
MinItemWidth="500" />
</ItemsRepeater.Layout>
<ItemsRepeater.Transitions>
</ItemsRepeater.Transitions>
<ItemsRepeater.ItemTemplate>
<DataTemplate DataType="viewModels:TvShowViewModel">
<Border>
<Border.ContextFlyout>
<MenuFlyout >
<MenuItem Header="{Binding TvShow.Name, StringFormat='Open {0}'}"
Command="{Binding OpenShowDetailsCommand}">
<MenuItem.Icon>
<avalonia:MaterialIcon Kind="OpenInNew"
Foreground="{DynamicResource ColorPrimary}" />
</MenuItem.Icon>
</MenuItem>
<MenuItem Header="{Binding TvShow.Name, StringFormat='Remove {0}'}"
Command="{Binding RemoveFavoriteCommand}">
<MenuItem.Icon>
<avalonia:MaterialIcon Kind="Delete"

</ItemsRepeater.ItemTemplate>
</ItemsRepeater>private void InputElement_OnPointerPressed(object? sender, PointerPressedEventArgs e)
{
if (sender is not Control control)
{
return;
}
if (control.DataContext is TvShowViewModel tvShowViewModel)
{
if (e.GetCurrentPoint(sender as Control).Properties.IsLeftButtonPressed)
{
tvShowViewModel.RemoveFavoriteCommand.Execute(null);
}
}

I know that ItemsRepeater will eventually be discontinued, so I tested using ItemControl and everything seems to work fine, even better than ItemsRepeater, the only thing that holds me back is the missing options that UniforGridLayout.
Are there any plans to have more options in UniformGrid or something that will eventually replace the UniformGridLayout that Item Repeaters have?
