Query loop can’t display multiple post types

I have four custom post types, and am using the following code snippet (using WPCode) to display them all at the same time in one query loop:

function filter_specific_query_loop($query) {
    // Check if this is an admin query or not the main query
    if (is_admin() || !$query->is_main_query()) {
        return;
    }

    // Check for the presence of the custom query parameter
    if (isset($query->query_vars['custom_query_loop']) && $query->query_vars['custom_query_loop']) {
        // Modify the query to include multiple post types
        $query->set('post_type', array('post', 'restaurants', 'activities', 'equipment','recipes'));
    }
}
add_action('pre_get_posts', 'filter_specific_query_loop');

// Add a filter to include the custom query parameter when rendering the block
function add_custom_query_var($block_content, $block) {
    if ($block['blockName'] === 'core/query') {
        if (isset($block['attrs']['className']) && strpos($block['attrs']['className'], 'custom-query-loop') !== false) {
            add_filter('query_vars', function ($query_vars) {
                $query_vars[] = 'custom_query_loop';
                return $query_vars;
            });
        }
    }
    return $block_content;
}
add_filter('render_block', 'add_custom_query_var', 10, 2);

I added custom class name: custom-query-loop to the query loop (located on home page). When I preview my page however, I only see one post type from the query loop.

Am I doing something wrong? My site is not live yet.

Thank you in advance for help!
