I also tried this approach, but this crashed the site with a fatal error:

function tas_pre_get_posts( $query ) {
    
    // do not modify queries in the admin
    if( is_admin() ) {
        
        return $query;
        
    }
    
    // only modify queries for 'post' post type
    if( isset($query->query_vars['post_type']) && $query->query_vars['post_type'] == 'post' ) {
        
        $query->set('orderby', 'meta_value');    
        $query->set('meta_key', 'tas_album_order');    
        $query->set('order', 'DESC'); 
        
    }
    
    // return
    return $query;

}

add_action('pre_get_posts', 'tas_pre_get_posts');
