Psychopy Unable to Connect with StimTracker

If this template helps then use it. If not then just delete and start from scratch.

OS (e.g. Win10): Mac OS Big Sur
PsychoPy version (e.g. 1.84.x): 2022.1.4
Standard Standalone? (y/n) If not then what?:
What are you trying to achieve?: We try to connect Psychopy with the stimtracker, use Psychopy to present stimuli, and send event markers to the stimtracker to record the onset times of our stimuli.

What did you try to make it work?:
We have downloaded and installed the USB driver on this website (D2XX Drivers - FTDI) in the Mac’s terminal, following the instruction in the Readme file.

What specifically went wrong when you tried that?:
We run the sample code from Cedrus on this website (https://cedrus.com/support/c-pod/psychopy_pyxid_test.py) in the coder, and we keep receive the error message below. Whenever we run that sample code, the light B under Code blinks (Please see the attached photo). It seems that we can sort of connect Psychopy with Stimtracker, but we are getting this error:

Could you please help us with this?

Thank you so much!
