Answer 1

1. Another case is Android Emulator should be reinstalled. This can happen, when you install a higher version of Android Studio, then update SDK for it, and go back to previous one.

   Tools - Android - SDK Manager - SDK Tools - Android Emulator - uncheck, apply, check, apply

2. Disable Docker app if you have it (Mac users).

3. Restart emulator:

   Tools - Android - AVD Manager (or kill adb process in task manager).
