Visual Studio Mac Deployment Failed to Android Emulator

Question

Trying to deploy a Xamarin Android App to an emulator running on a Mac fails with error "Deployment Failed" along with Mono.AndroidTools.AdbException: secure_mkdirs failed: Permission denied

Update: The emulator was started by Android Studio. When I try to start the emulator from Visual Studio Mac, I get error
