LightBurn only sends the command - the machine itself is what performs the homing operation, so the timing is a coincidence. You likely have a loose cable, broken wire, bent limit switch, or something along those lines. Also, check the switches to make sure they’re being contacted properly. I’ve seen at least two cases where a user added a drag chain or something else to help manage the wires and had it catch on the gantry, preventing the laser from getting to the home switch. ---
