Application isn't installed when I launched it from a static shortcut in Xamarin.Android

I recently added some shortcuts to my app. The app is working fine, and the Static Shortcuts are shown as expected:

However, when I do click on any of them, I'm getting the following error that prevents the app to be launched:

Application isn't installed

These are my XMLs:

This is an intro to the MainActivity class:

namespace tk.supernova.tmtimer
{
    [Activity(Label = "@string/app_name", MainLauncher = true, WindowSoftInputMode = SoftInput.AdjustPan)]
    public partial class MainActivity : AppCompatActivity
    {    
        protected override void OnCreate(Bundle savedInstanceState)
        {
            base.OnCreate(savedInstanceState);

            Platform.Init(this, savedInstanceState);

            var context = Platform.AppContext;
            var activity = Platform.CurrentActivity;
    
            SetTheme(Resource.Style.MyBaseTheme_NoActionBar);
            SetContentView(Resource.Layout.Main);

I know that my package name (tk.supernova.tmtimer.tk.supernova.tmtimer) is different from the main namespace (tk.supernova.tmtimer.tk.supernova.tmtimer). I also tried to use {applicationId}, but it didn't work. I have also checked several ideas in Stack, and none of them worked in my case. Furthermore, I cannot easily change the "wrong package name" because the app has been published in the Play Store for around 3 years.

Also, I am sure the package name is correct:

Furthermore, Android.App.Application.Context.PackageName returns tk.supernova.tmtimer.tk.supernova.tmtimer. The expected result.

Any idea what am I doing wrong?

P.S.:

• I'm testing in an emulator running Android 11.
• I even tested physically on my phone and didn't work.

I got a solution from a Microsoft Forum. I just added this property: Name = tk.supernova.tmtimer.MainActivity" to my MainActivity like this:

[Activity(Label = "@string/app_name", Name = "tk.supernova.tmtimer.MainActivity", MainLauncher = true, WindowSoftInputMode = SoftInput.AdjustPan)]
public partial class MainActivity : AppCompatActivity
{
    //...
}

I personally believe this is a Xamarin.Android bug. I don´t think it will happen the same in regular Android apps but if someone tests it feel free to add it to the comments section, and I´m going to update this answer.
