Command Palette crashes when a gallery extension manifest omits the optional homepage field

[ScymicX]

Microsoft PowerToys version

0.100.1

Installation method

GitHub

Area(s) with issue?

Command Palette

Steps to reproduce

1. Install or build PowerToys with Command Palette enabled.
2. Add a gallery extension whose extension.json does not contain a homepage field.
3. Open Command Palette.
4. Open the extension gallery.

For example, the Game Library Dock extension manifest previously omitted the homepage property.

✔️ Expected Behavior

Command Palette should handle a missing homepage field gracefully.

The homepage link can be hidden or left empty, but opening the gallery should not crash Command Palette.

❌ Actual Behavior

Due to a crash when opening the extension from the gallery:

[18:12:45.4391623] [Error] GlobalErrorHandler.cs::HandleException::69 System.ArgumentException: De parameter is onjuist.
