Unhandled internal error --> TypeError: 'NoneType' object is not subscriptable

Hi there,

When I opened PsychoPy, I got the following “unhandled internal error”

Traceback (most recent call last):
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\app_psychopyApp.py”, line 864, in onIdle
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\app\idle.py”, line 105, in doIdleTasks
_doTask(taskName, app)
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\app\idle.py”, line 142, in _doTask
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\app\pavlovia_ui\menu.py”, line 86, in setUser
if user is None and PavloviaMenu.appData[‘pavloviaUser’]:
TypeError: ‘NoneType’ object is not subscriptable

I’m running PsychoPy3 v2020.2.10. I just uninstalled then reinstalled PsychoPy standalone and then restarted my computer. I logged into Pavlovia and then restarted PsychoPy and got the same error.

I’m kind of at a loss, here. I have no idea what this means or where to go to solve the problem.
