Smooth Scroll Stopped Working

I use GeneratePress, and I have added the code:
//remove GP smooth scroll from back to top button
add_filter( ‘generate_back_to_top_js_args’, function( $args ) {
$args[‘smooth’] = false;
return $args;
} );
This was working fine, and now it is moving very, very slowly. I deactivated all plugins besides Elementor Pro and GeneratePress Pro. Still does not work correctly.
