When trying to add a camera, the camera list in the Camera Configuration window is empty. I can't figure out how to add my Sony camera. Previously, I've selected USB Disk in the import dropdown to select my camera. 

STEPS TO REPRODUCE
1. Open Camera Settings
2. Press "+Add"
3. Camera list on left is empty

OBSERVED RESULT
The camera list is empty. I don't know if this is a permissions issue. 

EXPECTED RESULT
I expected to see a list of camera as shown in the Camera Settings page in the Digikam documentation. (https://docs.digikam.org/en/setup_application/camera_settings.html#camera-settings)

SOFTWARE/OS VERSIONS 
macOS: 11.7.7 Big Sur


ADDITIONAL INFORMATION
If I try to select USB for Camera Port Option and guess the mount path, Digikam crashes when selecting the camera from import drop-down list.
