Right. This, or something like it, has come up a couple of times before.
It doesn’t look like there’s a proper solution for it unfortunately, but you could look at the discussion in those threads and see if there is anything helpful. As a general rule the easiest solution is to just run it out of the app if you can. It’s possible to add libraries to the app if there’s something that doesn’t come with PsychoPy that you need for an experiment.
