Thanks for posting this!
It looks like you have ended up in a sticky situation as a result of using really high scaling in the app, resulting in the “Close” button being hidden. This is what it looks like with a bit more screen real estate:
Unfortunately, the simulator will steal your input keystrokes - otherwise you could just highlight the button using your keyboard and pressed it that way…
Instead, try to make the window tall enough to see the “close” button somehow!
Kind Regards,
