Form not send

hello,
i want contact form only load on some pages so i add this code

// Stop loading Contact From 7 CSS and Javascript on all pages.
    if( is_singular () ) {
        $post = get_post ();
        if( has_shortcode( $post -> post_content, 'contact-form-7' ) ) {
            $check_cf7 = true;
        }
    }
    if( !$check_cf7 ) {
        wp_dequeue_script( 'contact-form-7' );
        wp_dequeue_style ( 'contact-form-7' );
    }
function wps_contact_form_7_check_dequeue() {
    //Set to false to be able to check against something
    $check_cf7 = false;
    // Page ID, title, slug, or array of such.
    // if ( is_page( array( 37, 'contact-us', 'Contact US' ) ) ) {
    // if ( is_page( 'contact-us' ) ) {
    if ( is_page( array( 213, 'PAGE1', 'PAGE2' ) ) ) {
            $check_cf7 = true;
    }
    //so therefore dequeue only if is false 
    if ( !$check_cf7 ) {
        wp_dequeue_script ( 'contact-form-7' );
        wp_dequeue_style ( 'contact-form-7' );
    }
}
add_action( 'wp_enqueue_scripts', 'wps_contact_form_7_check_dequeue', 77 );

i need the recaptcha also load only on the pages CF7 is usd, so i try this code

// recaptcha
add_action('wp_print_scripts', function () {
    global $post;
    if ( is_a( $post, 'WP_Post' ) && !has_shortcode( $post->post_content, 'contact-form-7') ) {
        wp_dequeue_script( 'google-recaptcha' );
        wp_dequeue_script( 'wpcf7-recaptcha' );
    }
});

After adding this the CF7 is not working, gettting error.
