1) change your filter to an acf/save_post filter with priority > 10 ensure that values are saved to the DB before you try using them.
2) Get the value of the relationhip field, unformatted, from the project post being saved.
$kuenstlerinnen_id = get_field ('project_to_kunstlerin', $post_id, false);
The above value could be an array
if (is_array(kuenstlerinnen_id)) {
$kuenstlerinnen_id = kuenstlerinnen_id[0];
}
get the last name field from the other post
$artist_nachname = get_field('artist_nachname', $kuenstlerinnen_id;
update the field on the project with this value
update_field('project_kunstlerin_nach_name_sort', $artist_nachname, $post_id);
