I created three AVDs base on Android Q (API 29), using these system images: Android 10(Google Play), Android 10(Google APIs), Android 10.
All of these emulators
I'm not sure why that's happening (it was happening to me to using API 29). I cloned the device in the AVD Manager and dropped the API down to 28 (Pie, Android 9) and I was able to successfully launch my app again.
