Cannot build apk in Release

[AMT-Cheif]

I'm working on MAUI app, I tested it on debug, and worked fine.
Then I tried to generate the signed apk as :https://learn.microsoft.com/en-us/dotnet/maui/android/deployment/publish-ad-hoc?view=net-maui-8.0
but it can't build:
XamlC error XFC0002: EventHandler "myButton_Clicked" with correct signature not found in type "mytestapp.MainPage".

here the xaml of the button:

<Button Text="DoSomething"
    x:Name="myButton"
    Clicked="myButton_Clicked"
    />

  private async void myButton_Clicked(object sender, EventArgs e)
  {
}

I'm not using MVVM. I also tried to delete the button and recreate it and event handler but still the exception, only on RELEASE.
And if i delete the button, I get the same error on the next button in the layout. The only way it build it removing event handler from xaml and putting it on code behind, for all controls. What am I missing??
