Port failed to open- already in use? Mac

I’ve been trying to reconnect my laser to my Mac for a week now, a few months ago with the same Mac and laser it worked fine. I’ve tried everything I could think of and after I updated the computer and tried to connect I get the port failed to open message. I tried looking for other posts like this but I couldn’t find one for ortur and Mac. I’ve unplugged it and plugged it back in. I’ve cycled it on and off in various orders and I’ve got no idea what to do.

What did you update, the OS, Lightburn, both?

Both, first lightburn then Mac OS

What Mac OS are you running now?

macOS sequoia 15.0.1

OK, a couple things to try. First go to File Menu> Preferences> Load prefs backup and choose one from before any of the updates. Restart Lightburn.
If that doesn’t work, File Menu> Preferences> Open Prefs folder. Delete Prefs.ini and prefs.ini.old and restart Lightburn.
What is your hardware and how are you connecting? Direct to USB C port or through a hub or what?

Look at the solution in this post.

I have no idea where the file menu even is, I’m using the usb cord provided with the machine into an adapter for usbc
