Strange issue here. I've just downloaded Android Q preview in my Android Studio to try it within an emulator. However, no matter what device type I select, when I start the emulator with the selected Q image I get black screen on the emulator without any kind of feedback. I've already tried to delete and recreate the emulator, as well as wiping its data. Below a picture of my emulator state at the moment. If I select another image of a different api version, everything works fine. Below the Event log error:
Emulator: Critical: UpdateLayeredWindowIndirect failed for ptDst=(736, 114), size=(300x21), dirty=(300x21 0, 0) (A device attached to the system is not functioning.) ((null):0, (null))

Would just keep getting a black screen with nothing for hours with the tablets. What helped was actually the OPPOSITE of what most people here are recommending: after setting the tick box for 'Use Host GPU' and setting the target to the highest android
