androidTV / googleTV cannot deploy to LEANBACK TV emulator - android-studio

why dont apps deploy to the android tv emulator. im just trying to use the basic leanback sample here https://github.com/android/tv-samples. it works with pixel API 30 phone emulator but when using the android tv emulator it just says "waiting for all devices to come online" even though the emulator has started.
both the phone and tv emulators were just created through android studio using android 11 api 30
nothing on google helps. this is specific to the tv emulator. the apps deploy the phone ok.

Android Studio. Not deploy/run app to emulator 4.3

Android Studio 2.3.2
Emulator 4.3

adb devices
List of devices attached
emulator-5554 device

Well you do have the APIS and other things necessary, so I think your emulator is just too slow to load, or not compatible with your PC , so its not loading.
