WooCommerce Memberships: exclude post loops on forced public pages

functions.php

// Initialize the global flag on the wp action hook
add_action('wp', 'initialize_force_public_page_flag');

function initialize_force_public_page_flag() {
    global $is_force_public_page, $wp_query;
    $is_force_public_page = false;
    if (!empty($wp_query->queried_object_id)) {
        $is_force_public_page = get_post_meta($wp_query->queried_object_id, '_wc_memberships_force_public', true) === 'yes';
    }
}

// Filter to make posts public for pages with _wc_memberships_force_public set to 'yes'
add_filter('wc_memberships_is_post_public', 'make_posts_public_for_force_public_page', 10, 3);

function make_posts_public_for_force_public_page($is_public, $post_id, $post_type) {
    global $is_force_public_page;
    // Check if we're on a page with the _wc_memberships_force_public key set to 'yes'
    if ($is_force_public_page) {
        // If so, make all posts appear as public
        return true;
    }
    return $is_public;
}

This snippet is helpful if you are wanting to show a preview of member post content in a post gallery or other custom loop on a public page. Simply enable the "Disable restrictions" on the page where you will be showing the custom member post loops and then will fully appear.
