Attach DevTools should only be called after application initialization is complete. A good point is OnFrameworkInitializationCompleted()

Example

C#

public class App : Application
{
   public override void OnFrameworkInitializationCompleted()
   {
      if (ApplicationLifetime is IClassicDesktopStyleApplicationLifetime desktopLifetime)
      {
         desktopLifetime.MainWindow = new MainWindow();
      }
      else if (ApplicationLifetime is ISingleViewApplicationLifetime singleViewLifetime)
         singleViewLifetime.MainView = new MainView();

      base.OnFrameworkInitializationCompleted();
      this.AttachDevTools(new Avalonia.Diagnostics.DevToolsOptions()
          {
             StartupScreenIndex = 1,
          });
   }
}
