I don't think your issue has to do with Navigation. Your App UI (A CollectionView with bindable layouts embedded) is quite intense and, on my machine, uses around 700 MBs just opening it and fully screening it on the main page alone. Scrolling down will cause the same WinUI exception you're seeing by navigation. You're also navigating to the same page instance, but removing and adding your item source. So you're not navigating to anything; it's the same page.

Looking at the debugger tooling (and turning off XAML Hot Reload) and scrolling through the list, it seems that Setter Specificity continually adds items to its list and doesn't remove them. For example, changing your app UI to

<CollectionView SelectionMode="Single"
				ItemsSource="{Binding ItemList}">
	<CollectionView.ItemTemplate>
		<DataTemplate x:DataType="local:Item">
			<Grid RowSpacing="0"
				  RowDefinitions="Auto,1"
				  ColumnDefinitions="120,*,120,64">
                <Label Text="{Binding Name}"
					   FontSize="24"
					   WidthRequest="120"
					   VerticalOptions="Center"
					   HorizontalTextAlignment="Center" />
            </Grid>
		</DataTemplate>
	</CollectionView.ItemTemplate>
</CollectionView>

and scrolling through the list,

The count and memory size seems to, generally, increase all the time. It could be that your app UI as designed, on top of possible memory issues with things like setter specificity, could be causing the problem.

@drasticactions 3Q ,yes!, Repeated Invoke Clear and Add can also cause crash
