Hello!~ I was trying to run a trial, clicked the ‘Run’ button, and the following error message came up. Could anyone kindly help out? Thanks in advance!

Traceback (most recent call last):

It looks like for whatever reason, time.localtime() is returning None. Do you have any custom packages installed, or any variables named time which might have overwritten it?

Thank you so much for your reply! It could be a problem with my own computer rather than PsychoPy. I will (try to) look into it!~
