iOS Simulator crashes after boot with "available but has no defaultDisplay"

While running a project into the simulator, it crashes after booting:

Crash: 'NSInternalInconsistencyException', reason: 'Device <redacted>, Booted) is available but has no defaultDisplay'

I already cleaned the project files and changed the iOS image but it crashes anyway. Any clue?

Close all simulators and just run 

sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService

to restart the service. All simulators will launch as usual.
