To follow up on this inquiry, I have temporarily solved this problem by following this forum (Audio library not appearing in Preferences (Mac)).
So what I did was to downgrade Psychopy to Version 2022.2.5, and then it works without any issues. After changing audio preferences (i.e., deleting sounddevice) I re-installed the up-to-date version (2023.1.2), but the launch error came back. So as long as I don’t find any permanent or better solution, I assume that I should keep using the older version.
