Many thanks for the feedback.
i changed it in my child theme as follows:

function register_assets()
{
    // Your existing wp_register_style and wp_register_script code

    $baguettebox_selector = apply_filters('baguettebox_selector', '.wp-block-gallery,:not(.wp-block-gallery)>.wp-block-image,.wp-block-media-text__media,.gallery,.wp-block-coblocks-gallery-masonry,.wp-block-coblocks-gallery-stacked,.wp-block-coblocks-gallery-collage,.wp-block-coblocks-gallery-offset,.wp-block-coblocks-gallery-stacked,.mgl-gallery,.gb-block-image');

    $baguettebox_filter = apply_filters('baguettebox_filter', '/.+\.(gif|jpe?g|png|webp|svg|avif|heif|heic|tif?f|)($|\?)/i');

    $script = 'window.addEventListener("load", function() {
    baguetteBox.run("' . $baguettebox_selector . '", {
        captions: function(element) {
            var img = element.querySelector("img");
            return img ? img.getAttribute("alt") : "";
        },
        filter: ' . $baguettebox_filter . '
    });
});';

    wp_add_inline_script('baguettebox', $script);
}

add_action('wp_enqueue_scripts', 'register_assets');
