Font Manager failed to load file

What specifically went wrong when you tried that?:
After updating to lates version of psychopy, I have not been able to run old experiments due to a font error. I also recently updated my Mac but pretty sure my experiments were working then. I have tried different fonts but keep getting the warning message below when the program shuts down after measuring frame rate. interestingly, when I push the study online on Pavlovia, the program does work, so just doesn’t local.

TypeError: rush() got an unexpected keyword argument ‘enable’
16.6527 WARNING Font Manager failed to load file /System/Library/PrivateFrameworks/FontServices.framework/Resources/Reserved/PingFangUI.ttc
######## Experiment ended with exit code 1 [pid:57648]

Which font are you using in your experiment?

Ive tried Open Sans and Arial

Could you share the full error? The warning about the fonts isn’t the reason for the crash I don’t think - it’s just warning you that one of your system fonts couldn’t be read in. The lines above “TypeError: etc.” are what tell you where the error happened.

below is the full message, thanks for reaching out.
