[Resolved] Pagination not working after pre_get_posts modification

Hey y’all. I recently modified my custom post archives to display alphabetically and it threw my custom single-post pagination off. What am I doing wrong? I’m sure I need to add another filter for the pagination, but not sure the right way to do it. The pagination is a block element set to “post navigation” and then container links are dynamic set to “next” and “previous” posts, respectively.

Here is the code I used to modify the archive page

function foo_modify_query_order( $query ) {
    if ( ! is_admin() && $query->is_main_query() && ! $query->is_post_type_archive('happenings') ) {
        $query->set( 'orderby', 'title' );
        $query->set( 'order', 'ASC' );
    }
}
add_action( 'pre_get_posts', 'foo_modify_query_order' );

Any help is appreciated, as always. Thank you!
