<Label Text={Binding .} /> works in Debug but not Release

Description

Trying to use a BindableLayout to display a List of strings, e.g. List MyStringList = {"Joe", "Mark", "Sarah", "Andy"}

Following xaml code works in the iOS Simulator & Android Emulator in Debug but not Release and not when published to an iPhone or Android phone. No text is displayed in Release

<VerticalStackLayout BindableLayout.ItemSource="{Binding MyStringList}"> <BindableLayout.ItemTemplate> <DataTemplate> <Label Text="{Binding .}" /> </DataTemplate> </BindableLayout.ItemTemplate> </VerticalStackLayout>

Also tried and both work on simulators not on devices.

dotnet version 6.0.301

Steps to Reproduce

1. Create a new Maui App
2. Add a List in the code behind
3. Add below code to xaml contentpage

[polygonsheep]

the bug report deleted my code.

Here it is again

<VerticalStackLayout BindableLayout.ItemsSource="{Binding MyStringList}"> <BindableLayout.ItemTemplate> <DataTemplate> <Label Text="{Binding .}"/> </DataTemplate> </BindableLayout.ItemTemplate> </VerticalStackLayout>

More info, if you add the DataType to the DataTemplate the text will show up in Release mode.
<DataTemplate x:DataType="x:String">

The DataType is not required in Debug mode.
