Theme Appearance is ‘broken’

Hi,

I was trying to change the appearance of my child-theme by editing the functions.php file -the changes i was making didn’t work, so i deleted them and restored the functions.php file to its original state: the Site is not loading as it should anymore. To confirm, everything was working as it should before i touched the file.

Does anyone have an idea of what’s gone wrong?

Functions.php looks like this:

<?php
function my_theme_enqueue_styles() {

    $parent_style = 'scrawl';
    wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css' );
    wp_enqueue_style( 'child-style',
        get_stylesheet_directory_uri() . '/style.css',
        array( $parent_style ),
        wp_get_theme()->get('Version')
    );
}
