Thank @jflatnes I had not checked properly if Imagick worked, as the Image Magick kept sending an error in System Info. So that’s settled.
My issue looks similar to this one CSV Import 'PHP-CLI error: job script failed to execute - #3 by TestingItOut
But exec and proc_open are not marked as disabled. Here is my full System Info :
