All winui3/wasdk packaged app crash upon launching in admin mode on Windows 10

[HO-COOH]

Describe the bug

I found out all winui3 / wasdk packaged app (no matter C# or C++) crash upon launching in admin mode on Windows 10 (I tested Windows 10 17763 and 19041 LTSC, exactly the same result).

Curiously, the crash does NOT happen when running with debugger inside an elevated Visual Studio. And it also does NOT happen when using unpackaged mode.

The crash dump doesn't reveal much information and it does not happen in a debugger, making it's quite hard to figure out the reason.

Steps to reproduce the bug

1. Create an empty winui3 packaged app
2. Builld and deploy.
3. In start menu, right click the app >> Run as administrator

Expected behavior

No response

This is not a Windows 10 issue, but rather an architectural problem:

@Balkoth Maybe, but launching them the exact same way under Windows 11 does not crash.

This is a runtime issue about activating a packaged app. This may be WinAppSDK, or maybe external (Windows).

Regardlesss, it's not an MSIX deployment tech issue so I've removed the area-PackageManagement tag
