Issues with moviepy

Psychopy version : 1.90.3

MacOS - 10.7.5 - Lion ?

//The scripts works perfectly on my MacBookPro (Mojave), same psychopy version.//

The stimulus runs and I get the introduction screen, at the initialization of the stimuli (movie) it crashes with the errors (in the attached images).

I get the following errors on the MacOS Lion 10.7.5


I have tried the following:

Installing avbin - and changing moviepy to avbin in the psychopy builder, MovieStim dialog box.

Is there anything that I maybe missing, it has XCode installed (2012). It is a stimulus computer for the lab, so I may not be able to make permanent changes to things as it could affect other users.

Any help will be appreciated.

EDIT: the demo movies also don’t work.
