Error launching experiment to Pavlovia from PsychoPy

Hello Everyone,
OS (e.g. Win10): MacOS Sierra
PsychoPy version (e.g. 1.84.x): PsychoPy v2020.1.2
Standard Standalone? (y/n) If not then what?: yes?
What are you trying to achieve?:
I want Pavlovia to launch my task that is set for CM rather than pixels
What did you try to make it work?:
I have restarted my computer, restarted PsychoPy and I played around in the Experimenter settings and changed them to CM. Additionally, I have looked through the comments on a similar problem where they suggest going to Preferences /App/ Reset Preferences. This has not worked either.
What specifically went wrong when you tried that?:
The same error message came up

Thank you for your time.
