Laser will not come on after 1 use

Hi, my laser worked once and won’t come on again. The fan run but no light. I used code M3 S255 but that didn’t help either. In the code box, I saw something called laser protection mode. Can someone please help me with this? Thank you

“Laser Auto Protection” This warning message is a protection function added by Dexarm to prevent excessive burning in a certain fixed position.
If Dexarm does not receive a move gcode command within one minute after the Dexarm laser is turned on, it will automatically turn off the laser and throw out “Laser Auto Protection”.

I want to confirm,your laser module model,2.5W V1 or 2.5W V1.2?
