I’m having an issue when I try to launch Psychopy3 from the shortcut. I’m using Windows 10 and installed standalone Psychopy 2020.2.4 for 64 bit Windows.
Then, I typed like the below on command prompt as Psychopy official page (https://www.psychopy.org/troubleshooting.html) said.
“C:\Program Files\PsychoPy3\python.exe” -m psychopy.app.psychopyApp
and, I got this error.

However, I’m not sure how to deal with this error.
Does anyone know how to fix this problem?
