Trying this on Android, I couldn't get this to crash on the template app, as you suggested.

Can you post what your workloads you're currently running? You can use 'dotnet workload list' to get them.

I am using VS 2022 preview (latest). I just create a clean template Maui app (with the "clicked N times" example).

I compile it, it works fine.

I modify the MainPage.xaml, adding the IsBusy = "True" as in:

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="MauiAppCleanTemplate.MainPage"
             IsBusy="True">

Try to run again, and I get the unhandled exception right away.

We've moved this issue to the Backlog milestone. This means that it is not going to be worked on for the coming release. We will reassess the backlog following the current release and consider this item at that time. To learn more about our issue management process and to have better expectation regarding different types of issues you can read our Triage Process.

Okay, I was able to reproduce this.

If you have a app using Shell, and set "IsBusy" to "true" as the default on the page, that will cause the app to explode. If it's not set to true when you run the app and set it after the fact, it works fine. Moreover, it seems only to affect Shell apps. If"MainPage" is the rootview, it works fine.
