Bluestacks is basically an android gaming emulator. Thus, switching up its graphics mode is also known to be an easy fix to the engine won’t start issue as well. By default, Bluestacks runs via OpenGL, however, it can also be run via DirectX. The option in order to make the switch is present in Bluestacks settings.

If merely changing the graphic mode doesn’t really work. Then you can always increase the number of CPU cores and RAM allocated to Bluestacks and also provided it a little more juice to run.

If you guys receive the ‘engine won’t start’ error message again, then simply ignore it for the time being.
