Start by reproducing the crash with a WinUI 3 app built with Windows App SDK 1.6.1 on Windows 11 build 22621: launch the executable as administrator, then use Windows Key + Arrow Up before interacting with the tool. Capture the crash event and determine which window-resize path fails; done means the application resizes successfully without closing.
