Alarm 9: Homing Fail - laser doesnt move to home

Hello all,
I have a newer k40+ was working last week, but I switched lightburn from my Ortur diode laser back to the k40 which I have done numerous times with no issues, it shows ready but when I home this is the error I get:
ALARM:9

Homing fail. Could not find limit switch within search distance. Defined as 1.5 * max_travel on search and 5 * pulloff on locate phases.

Now, when I try to switch back to my ortur which I was using yesterday, it also states the port is already open. So neither laser will connect correctly. I just updated lightburn and my MAC OS.

Check the COM ports in Windows device manager. Those might change from time to time.
