When I switched to launching the Android Emulator from the Command Line instead, I finally got to see an error message: $ cd $(dirname $(which emulator)) &. Every time I launched it from Android Studio it would start, but then – without any errors or warnings – close all by itself. On a recent project I was working on, I wasn’t able to start the Android Emulator/Simulator anymore from within Android Studio. Make sure you’re running the latest version of Android Studio UPDATE 2017.08.03: This should be fixed with the release of HAXM 6.1.1.
