Custom Block + Custom Post Types = wp.blockEditor is undefined

Hello,

I made a few Custom Blocks and they work fine in posts and pages.

In custom post types I get the message the console that wp.blockEditor is undefined, and I can’t use the blocks.

I think I am forgetting something when I declare my CPT, but can’t find what. I’ve also search the whole morning on the net and can’t find any reference to that issue :/

Here’s how I register the CPT and the Block:

function q_product_cpt() {

    if( function_exists('register_post_type') ) :

        $lables_cpt_product = array(
            'name'                  => _x( 'Products', 'Post Sector General Name', 'q_product' ),
            'singular_name'         => _x( 'Product', 'Post Sector Singular Name', 'q_product' ),
            'menu_name'             => _x( 'Products', 'Admin Menu text', 'q_product' ),
            'name_admin_bar'        => _x( 'Product', 'Add New on Toolbar', 'q_product' ),
            'add_new'               => __( 'Add New', 'q_product' ),
           ...
        );

        $args_cpt_product = array(
            'label'                => __( 'Products', 'q_product' ),
            'description'          => __( 'Products', 'q_product' ),
            'labels'               => $lables_cpt_product,
            'supports'            => array( 'title', 'custom-fields', 'editor', 'author', 'revisions', 'page-attributes' ),
            'hierarchical'         => false,
            'public'               => true,
            'can_export'           => true,
            'has_archive'          => true,
            'exclude_from_search'  => false,
            'capability_type'      => 'post',
            'show_in_rest'         => true,
        );
        register_post_type( 'product', $args_cpt_product);

    endif;
}

add_action( 'init', 'q_product_cpt', 0 );

Here’s how I register the Block:

add_action( 'init', function() {
    wp_register_script('quasi-header-js', plugin_dir_url( __FILE__ ) . 'template-parts/blocks/quasi-header.js');
    register_block_type('quasi/header', [
        'editor_script' => 'quasi-header-js',
    ]);
}, 10);

And the actual error message in the console:
Uncaught TypeError: can't access property "RichText", wp.blockEditor is undefined. I have this message even when I create an empty block and try to desctructure the RichText component

Thank you!
