Unable to launch the Surface DUO Emulator with Visual Studio

Dear Team, I have been facing issues with the Duo Emulator launch with the Visual Studio 2019, as the emulator not shows in visual studio build option(<build> (Android 10.0 - API 29) ).  I have followed the official instruction . So far I didn’t find any solution. Below am giving the details.

Problems 

• Unable to launch the emulator directly after modified run.bat file:  When I click the Surface Duo Desktop Icon a command prompt launch and suddenly go to crash.
• <build> (Android 10.0 - API 29) : emulator not appear in VS-Xamarin 2019 build option

Things I done

• Followed the  official Doc instruction : installation (VS 2019- Xamarin , Surface Duo emulator, Xamarin Android SDK Manager Emulator option checked ),  run.bat  file modification, Hyper V enabled.
• Installed the Android Studio

Things that works (before modifying run.bat )

The emulator successfully launch with the Android SDK (run_androidstudio.bat😞 I have already installed VS 2019 with Xamarin. And once I installed the Surface Duo emulator, I try to directly launch the emulator by clicking emulator icon, however its not respond, then I installed the android studio and tried again, and it was successfully launched.

Please advise, Thanks.
