I’ve been using Psychopy3 (v2020.2.10) on my old lap-top and there was actually no problem at all.
As I’ve recently bought a new lap-top, I’ve downloaded the recent version of Psychopy & Python.
Opening the “Psychopy program” is no problem.
I can even build my experiment on the builder.
I was trying to show a class how to use Psychopy, so I made a very simple task as below:
I only have 6-7 audio files in “.wav” and uploaded them using a loop (excel file uploaded).
When I click on the “run experiment”, the insert-box for “Participants” appears.
However after typing in any name and as I press enter an error message appears.
The first error message was this:
1060.3271 INFO Loaded monitor calibration from [‘2021_05_09 13:50’]

4.8513 WARNING We strongly recommend you activate the PTB sound engine in PsychoPy prefs as the preferred audio engine. Its timing is vastly superior. Your prefs are currently set to use [‘sounddevice’, ‘PTB’, ‘pyo’, ‘pygame’] (in that order).
35.5479 WARNING User requested fullscreen with size [1024 768], but screen is actually [1920, 1080]. Using actual size
To Solve:
-
I went to “Preferences” and changed the order as following:
[PTB, sounddevice, pyo, pygame] -
I’ve realized that my computer setting for the screen size is somehow fixed to [1920, 1080] and can’t change it.
So I changed the screen setting on my Psychopy builder to [1920, 1080] as following:
After doing the above 1 & 2, I clicked on the run experiment again and entered a participant name.
Then a gray screen(ish) appears for a few seconds and shuts down again, leaving the following error message:

Now I’m really stuck…
Funny thing is the same error message appeared on many of my students this semester.
(especially the above number 1&2 problems)
I’ve been doing this “Psychopy introduction” almost every semester,
but this semester is quite unusual…
Can someone please help me?? 
Thank you very much for your help!!!
