Green screen when i take a picture with pygame on jetson nano

[Achta00]

When I take an image with the camera ( Camera V2 raspberry) with the pygame or cv2 module, I get a green screen.
I looked for several documentations to solve this problem but never anything very specific.

Do you have any idea?
