After updating AS now emulator quits every time I start it. Below is the screenshot I managed to capture before it disappeared.
In the logs the following are printe
I experienced the same issue when updating Android Studio to version 3.4.
What worked for me was editing the AVD configuration and on Graphics I selected "Software -GLES 1.0". This made my emulator successfully boot up again.
Then I just went back to the Graphics configuration and selected "Hardware - GLES 2.0" again, which made my emulator go back to its usual performance.
Hope that helps!
