mlaunch fails to list AppleTV paired with Xcode

[viniciusjarina]

mlaunch fails to list paired AppleTV device causing VSMac/Rider to not show AppleTV device. The device shows normally on Devices & Simulator

Xcode 15.3 15E204a
macOS 14.4.1
Xamarin.iOS Version: 17.2.0.43 Visual Studio Community - Hash: 2cb9d6666

viniciusjarina@JarinaM3:~$ /Library/Frameworks/Xamarin.iOS.framework/Versions/Current/bin/mlaunch --version
Xamarin.Launcher 1.0.83 (refs/heads/main: 699ed5eaf2)

Steps to Reproduce

1. Launch mlaunch with --listdev -v

2. Get NullReferenceException:

error MT0000: Unexpected error - Please file a bug report at https://github.com/xamarin/xamarin-macios/issues/new
System.NullReferenceException: Object reference not set to an instance of an object.

What's the exact command you're executing, and the output you're getting?

Which mlaunch version are you using?

@rolfbjarne sorry I click save before I was finish with details.

Can you try using the mlaunch in this NuGet, and see if that works better?

https://dev.azure.com/dnceng/public/_artifacts/feed/dotnet-eng/NuGet/Microsoft.Tools.Mlaunch/overview/1.0.162-ci.pr.gh2813.162%2006007cf77d

I can't reproduce this, so we might have to iterate a few times until it's fully working.
