Was working fine yesterday then today says laser disconnected

Loose cable?
Had this happen before and a quick check for physical wiring/USB cable was the culprit.
Then I had to shutdown the PC and reboot to get LightBurn to see the device but it’s working fine now.
I should add that I incorporated a strain relief to the cable that plugs into the laser cabinet. It’s simply a magnet with a hook stuck slightly above the USB port and a wire tie to hold the end of the cable more securely in place.
