WinUI 3 Gallery crashed when clicking Settings button

[MelodyBuffer]

WinUI3 Gallery crashes consistently when clicking the setting button.

Step1. Open WinUI3 Gallery.
Step2. Click the bottom-left Settings button.

Then after one pause, the software crashes without any messagebox or error warning or logs.

Some details:

• System version: 22621.3007
• MS Store version: 22312.1401.5.0
• WinUI3 Gallery version: The latest version availible from Microsoft Store as of this post of this issue.
  Ok, you know I even can't open the settings page:(

Hmm, I'm unable to repro this issue. Can you sent the error logs from Event Viewer that correspond to the crash? Also, if you are able and find the time, you trying to build and run the app from source would help identify the issue further.

Hello, I've just builded version from eb43dce and I'm experiencing same issue. It's InvalidOperationException: "Sequence contains no elements"; attaching my local stack trace, hope it'll help:
