This week, I created a new task in using PsychoPy Builder 2021.1.1 installed using Anaconda on Windows 10. It was working fine on my local machine.
Sometime between then and now, I updated the packages in my Anaconda environment and inadvertently updated psychopy to version 2021.1.3. When I saw this, I immediately downgraded back to psychopy 2021.1.1. When I went to work on my script today, I kept getting the following error message whenever I try to run the same task. I also tried creating an entirely new task (i.e., File > New) and tested whether it would run using one routine with (1) a text component, (2) a text and keyboard component, but get the same error message. I will include the full output.

Its timing is vastly superior. Your prefs are currently set to use ['sounddevice', 'PTB', 'pyo', 'pygame'] (in that order).
I have tried troubleshooting everything I could think of, including removing the Anaconda environment and recreating it from scratch. This is the environment.yml file I have been using:
name: lsantasks channels: - conda-forge dependencies: - python=3.6 - psychopy=2021.1.1 - pip - pip: - psychtoolbox - pygame - pyo - pyparallel; platform_system != "Windows" - SoundFile; platform_system == "Windows" - websocket_client
I have a previous version of psychopy (v2020.2.4) in a different Anaconda environment and it can successfully run new tasks without any error.
Please advise on what I can do to fix this issue.
Thanks so much for your help!
