PowerToys Run crashes with NullReferenceException when launching an unlaunchable MSIX/UWP app

[nadeshikochan]

Microsoft PowerToys version

0.96.1.0

Area(s) with issue

PowerToys Run / Program plugin

Steps to reproduce

1. Have an MSIX/UWP app that Windows currently cannot launch. In my case it was the ChatGPT/Codex desktop app.
2. Open PowerToys Run with Alt+Space.
3. Search for the app and press Enter.
4. PowerToys Run crashes.

Expected behavior

PowerToys Run should report that the app could not be launched and remain open.

Actual behavior

PowerToys Run crashes with:

System.NullReferenceException: Object reference not set to an instance of an object.
at Microsoft.Plugin.Program.Programs.UWPApplication.<>c__DisplayClass64_0.<Launch>b__0()
at Microsoft.Plugin.Program.Programs.UWPApplication.Launch(IPublicAPI api, String queryArguments)

Environment

Windows 10.0.26200.0, x64
PowerToys 0.96.1.0

Additional information

I reproduced this three times. Repairing the affected app in Windows Settings temporarily made it launchable again.
