Hi NN81 thanks for your answer.
I exported without touching anything, so all three options (Window Frame, Rezisable Window, Kiosk Mode) were indeed enabled.
I've tried to disable Kiosk Mode, and now the game doesn't open in FullScreen anymore but in Windowed. The FullScreen toggle then works just fine and there is no more crash. So this solves the problem ! Nice !
Thanks a bunch !
One last thing : can you explain what the Kiosk Mode is supposed to do ? Am I losing something by not enabling it in my project ?
i think the answear is same spoked in the manual:
Kiosk mode: use a "kiosk" display mode, where the app runs in fullscreen and tries to prevent the user from leaving.
i think that with your windowed/fullscreen choice events, this cause the issue
