Error running DARKTABLE and gphoto2 on Mac Mini x86 (Monterey) and M2 (Sonoma)

When running darktable and attempting to connect to Nikon D300s camera, I get a message indicating no attached camera.
I ran gphoto2 and captured logs as described in troubleshooting part of user manual.

I don’t see any place where any other app has the USB port locked, but there does seem to be an issue here.
Any ideas?  Log file attached.
