Try check the event viewer and see if there is any error logged there.
What app is being loaded in the Kiosk mode?
Is there anything in event viewer?
I would suggest you to use proc mon to identify if there is nothing on the event viewer.
Try updating the graphic card driver for the device.
User account control (UAC) must be turned on to enable kiosk mode.
Kiosk mode is not supported over a remote desktop connection. Your kiosk users must sign in on the physical device that is set up as a kiosk. Apps that run in kiosk mode cannot use copy and paste.
Hope this resolves your Query !!
