Ok. So downgrading to 3.2.3 as @Hannah says and making sure PsychoPy has access to input monitoring does _not_ fix the problem for me. So as far as I can tell there is no way for me to run PsychoPy experiments on this machine with Catalina. I’ve not yet tried going back to even earlier versions of PsychoPy.

EDIT: This _does_ work if you downgrade to 3.2.3 if you also go into Settings \> Security & Privacy \> Privacy \> Input Monitoring and remove PsychoPy3 then let it add itself back again. 🙂
