[SOLVED] heap corruption windows 10

In our Windows 10 UWP app we are suffering from Heap corruption during random page navigations. The timing and location is always different yet the same result is there, Heap corruption when Native debugging is turned on and an immediate crash when it's turned off.

Below is the callstack at the time of the heap corruption with as much info as we've been able to gather from Visual Studio.

Any chance anyone has encountered this exact, or close to issue and managed to resolve it? Thanks in advance.

EDIT! Got some new info! sadly no fix yet but progress... :)

Turns out the issue is caused by the VisualStateGroups used to create an adaptive interface seen below:

<Style TargetType="controls:CollectionView">
    <Setter Property="RelativePanel.AlignLeftWithPanel" Value="True"/>
    <Setter Property="RelativePanel.AlignRightWithPanel" Value="True"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="controls:CollectionView">
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="*"/>
                    </Grid.RowDefinitions>

                    <GridView x:Name="List" 
                              Grid.Row="1" 
                              BorderBrush="Black" 
                              ItemsSource="{TemplateBinding ItemsSource}"
                              ItemTemplate="{TemplateBinding ItemTemplate}"
                              SelectedItem="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=SelectedItem, Mode=TwoWay}"
                              ShowsScrollingPlaceholders="False"
                              Background="Transparent"
                              RelativePanel.AlignLeftWithPanel="True"
                              RelativePanel.AlignRightWithPanel="True">
                    </GridView>

                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup>
                            <VisualState x:Name="UnSelectable">
                                <VisualState.StateTriggers>
                                    **<StateTrigger IsActive="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=IsNotSelectable}"/>**
                                </VisualState.StateTriggers>

                                <VisualState.Setters>
                                    <Setter Target="List.Background" Value="#AAAAAA"/>
                                    <Setter Target="List.IsHitTestVisible" Value="False"/>
                                </VisualState.Setters>
                            </VisualState>
                        </VisualStateGroup>
                    </VisualStateManager.VisualStateGroups>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

if i disable the above statetrigger the app will not crash, sadly i need the logic inside this state... any work arounds possible or an explanation what i am doing wrong?
