The machine may be busy

I added my laser machine to Lightburn but it shows “The Machine may be busy or paused” when i try to print it.

What laser do you have?

Looks like a corrupted firmware. I’d suggest reflashing the firmware to see if it can be remedied.

As PY mentioned, in the console window you can see boot messages of the controller stating that there is no firmware found to start from. You need to flash the firmware again to make it work. It’s a ESP32-based board, use the MKS flash tool to upload new firmware (I guess your manufacturer should have a complete package and instructions how to do so).
