Keep receiving the warning message of 'Pychopy 3 error'

This looks like the same error which another user found the other day, I’ve pushed a fix out for the next version but you can use the same solution for a quick fix:

Psychopy Error after removing experiment info fields

This is an area we’ve not changed for a while, so this bug must have been there a while! Thanks for catching it, I’ll work on a fix now. In the mean time, you can fix your experiment by opening the .psyexp file in a text editor (e.g. notepad) and replacing this line: <Param name="Experiment info" updates="None" val="{}" valType="code"/> with this: <Param name="Experiment info" updates="None" val="{'participant':''}" valType="code"/>
