Xamarin App opens different Page from Navigation.PushAsync() Page - xamarin

Question

Description
Xamarin application opens different Page upon NavigationPage.Pushaync().
NavigationPage.Asyncpush() is called within a ButtonClicked Method.
That different page used to be the one being pushed but it no longer is.
ViewModel.cs
private async void OnAboutUsClicked()
{
var modifiedContactUs = new ModifiedContactUs() { BackgroundColor = ResourceColourModel.BackgroundColor };
await Application.Current.MainPage.Navigation.PushAsync(modifiedContactUs);
}
ModifiedContactUs.xaml

Expected behavior
To navigate to a new Page named ModifiedContactUs
Actual behavior:
Navigates to page called named ContactUs
Basic Information:
Android Build:
-minimum level 21
-Target level 30
Devices:
-Huawei Y6 2019
-API level 29
-Pixel 5
-API level 30
Notes
This question is different to from the first question I asked recently (Where the device crashes). This is behavior happens on all devices I test on except the one from that first question

Answer 1

Expected behavior
To navigate to a new Page named ModifiedContactPage
Actual behavior:
Navigates to page called named ContactUsPage
From your code I saw you just push to ModifiedContactUs not ModifiedContactPage .
var modifiedContactUs = new ModifiedContactUs() { BackgroundColor = ResourceColourModel.BackgroundColor };
await Application.Current.MainPage.Navigation.PushAsync(modifiedContactUs);
Suggestion
Try to add breakpoint to see if it triggers button click event es expected .
Delete the old class and try again .
Delete the app from the device and try again .

Answer 2

This worked: Clone the repo into a new folder as a new project and copy the files and changes to this new repo.
Attempted configuration solutions that did not work: Restarting visual studio. Untick and Tick Debug Mode. Untick and tick Deploy in Configuration Manager under Build. In Android Properties> android Options making sure debugging is checked and debugger is Xamarin.
