First time using the Laser module

Hi, I’ve been using the 3D Print module for so many months and happy with it. But today for the first time I’m having problems with the laser module, stuck at Engraving — Processing page even though the auto focusing task was completed. I can’t select anything on the touch screen. Hope anyone here can give some advise. thank you.

Additional Info: I never used the laser module util the last update of the firmware from V1.11.4 to V1.12.0
