Serial Port EEGbiosemi

Hi there,
I ask for your help with the trigger sending via Serial Port EEGbiosemi. I’m using Windows 10Pro and Psychopy v2022.2.5 sith USB Serial Port recognize as COM3, and the same USB serial port showed here by Stephanie_Aedo (the only difference is the bits per seconds which in my case are = 9600).
I have been trying to run in my experiment all the solutions I have seen here in the forum. However, I’am at a loss to understand the multiple errors that appear and have decided to follow a tip I saw around here: to run a simple experiment first so I can indentify the main error. I took this one: trigger_test

I have it set up like this

Serial

…And the errors it yields are:

I would be grateful for any guidance in this regard.
Thanks in advance
