Hi,
I’ve recently encountered a bit of a snag while working with PsychoPy and was wondering if anyone else has experienced something similar or has insights on how to troubleshoot it.
The Issue: I’ve been encountering a launch error when trying to run my experiments in PsychoPy. It worked fine until yesterday when I tried to change the name of the .pyexp file created using builder. I’m curious if anyone else has come across this issue and, if so, how you managed to resolve it.
Additional Context: I’ve been running the latest standalone app on macOS 13.5.1, and I’ve followed the recommended installation steps. The error message I’m encountering is “Launch error See the py2app website for debugging launch issues”
What I’ve Tried: I’ve attempted debugging as the py2app website suggests and re-installed Psychopy. Unfortunately, none of these steps have seemed to fix the issue. I’m attaching the error log at the end of this post.
If anyone has any suggestions, workarounds, or insights on how to resolve this launch error, I’d greatly appreciate your input.
Thanks in advance for your time and expertise!
Best regards,
Heemin
