Answer 4

This can happen on slow computers when the emulator doesn't start in time. When it eventually does start, it is no longer connected to ADB. The solution is to restart ADB so that it reconnects to the emulator. You can do this by executing the following in command line:

adb kill-server
adb start-server

Answer 5

Disable snapshot and don't use it. It is what solved this issue in my case

Answer 6

Maybe it's an AVD problem for existing machine. Try to create a new AVD from the AVD Manager and delete the old one.
