WP_query does not work correctly in front-page.php template. how to find the reason?

Question

WordPress

Greetings!
there is a code:

//посты которые исключить
$community_not_in_query = new WP_Query([
  'post_type' => 'post', 
  'posts_per_page' => -1,
  'editors' => 'community', 
  'fields' => 'ids',
  'meta_query' => 
]);
$community_not_in = $community_not_in_query->posts;

$args = array (
    'post_type'              => array( 'post' , 'event'),
    'posts_per_page'         => 30,
    'ignore_sticky_posts'    => false,
    'post__not_in'           => $community_not_in
);

$query = new WP_Query( $args );
if ( $query->have_posts() ) : 
    while ( $query->have_posts() ) : $query->the_post();
        echo get_the_title().'</br>';
    endwhile;
endif; 
wp_reset_postdata();

the first request generates an array with id. posts, in the second we generate a feed of posts and exclude posts from the feed using the "post__not_in" parameter. So this code does not work in the front-page.php template, unnecessary posts still end up in the feed. The most interesting thing is that if the same code is run on any other page (for example, page-[single].php), then everything works correctly.

Tell me, what could be the reason for such a bug, the second day I'm racking my brain(
