I can confirm this behaviour on Windows 11 in a WinUI3 C# Desktop App.
Just put two fingers on the TouchScreen and move the Mouse ...
-> App is terminated.

This crash is still present in the latest stable version of Windows App SDK 1.2.

The Crash is still present in the latest Windows App SDK 1.3.3 (1.3.230724000) (released 07/25/2023).

So I don't think this issue should be closed!

Is anybody working on this issue?

@chrkon Yes, a fix was checked in a few days ago and is currently going through additional testing.

This issue seems to be fixed in WASDK 1.4.230811000-preview2 . Although, Simultaneous Pen and multi-touch still produce a similar crash. Please fix the Pen + Touch crash, this crash is a HUGE issue for any Pen apps using WASDK .

Fixed in 1.4.0. @bpulliam please close this issue as I cannot. :)
