I think the cf7-blocks-integrate script and styles are only needed for the block editor, right?
They are loaded in the frontend at the moment.
Temporary fixed with:
add_action( 'wp_enqueue_scripts', function () {
if ( ! is_admin() ) {
wp_dequeue_script( 'cf7-blocks-integrate' );
wp_dequeue_style( 'cf7-blocks-integrate' );
}
}, 100, 2 );
