bug: can't use Menu2 in system7 devices in the simulator

SDK 6.4.2, I use Menu2, and it works on devices like fenix6, but it doesn't work on devices like fr255 since the newest update of the devices a few days ago. I think it's down to the addition of CIQ 5.0.0 to these devices. I checked it on a real fr965 and it works, so the problem is only in the simulator.

Error: Unhandled Exception
Exception: UnexpectedTypeException: Unexpected title type, expected String, string ResourceId, or Drawable

the code:

    function onMenu() as Boolean {
        WatchUi.pushView(new Rez.Menus.MainMenu2(), new MyDelegate(), WatchUi.SLIDE_RIGHT);
        return true;
    }
