LightBurn can’t find my laser

Dear all,
Sorry for my bad english.
I have a DIY laser machine with diode laser. I have buy LightBurn license and use it well.
But when I change my laptop and try to connect, the Device Discovery Wizard can not find my machine. I has tried the Create Manually way but still cant connect.
My old laptop is Macbook Pro with Mojave
My new laptop is Macbook Pro with Monterey.

I have attached the video.

Please help. Thank you so much.

I love homebuilt machines.

Which controller board and GRBL did you flash into it?
Does it use the common CH340 USB/ serial chip?
