Why does the "Test Connection" for Bluetooth fail in the hardware setup screen for the Arduino support package on macOS versions 12, 13 and 14?

I am using an Arduino Uno with an HC-05 Bluetooth module, intending to integrate it with the MATLAB Support Package for Arduino Hardware on my Mac running Ventura OS 13. While I can successfully program the board via the hardware setup screen, the "Test Connection" button consistently triggers a prompt outside of the MATLAB window requesting a device connection. Despite clicking "Connect" on this prompt, the test connection fails in the hardware setup screen, preventing further progress.

This issue also occurs on macOS 12 Monterey and macOS 14 Sonoma.
