  • The post ID is not needed here

    update_sub_field('object_price', $newPrice, $r->post->ID);

    just like it is not needed here

    $projectPrice = get_sub_field('object_price');

    In addition to this $r->post->ID in incorrect by your code, this value is probably not defined and it causing update_field() to work incorrectly.
