why page 2 not working in wp query - php

Question

Why http://localhost/wp/?paged=2 and older not working in wp_query?
I have movie and series from "custom post type" more than 15 posts.
It's separated in 2 pages in the front-end, but when I press the older post, the page is still first page.
Here is my index.php loop code:
<?php
$paged = ( get_query_var('page') ) ? get_query_var('page') : 1;
$query_args = array(
'post_type' => array('post','series','movie'),
'posts_per_page' => 10,
'paged' => $paged
);
$the_query = new WP_Query( $query_args );
?>
<?php if ( $the_query->have_posts() ) : while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<h1><?php the_title();?></h1>
<?php endwhile; ?>
<div class="col-md-12">
<?php if ($the_query->max_num_pages > 1) { // check if the max number of pages is greater than 1 ?>
<nav class="prev-next-posts">
<div class="prev-posts-link">
<?php echo get_next_posts_link( 'Older Entries', $the_query->max_num_pages ); // display older posts link ?>
</div>
<div class="next-posts-link">
<?php echo get_previous_posts_link( 'Newer Entries' ); // display newer posts link ?>
</div>
</nav>
<?php } ?>
</div>
<?php wp_reset_postdata(); ?>
<?php else: ?>
<article>
<h1>Sorry...</h1>
<p><?php _e('Sorry, no posts matched your criteria.'); ?></p>
</article>
<?php endif; ?>

I've found a solution:
add_filter( 'pre_get_posts', 'my_get_posts' );
function my_get_posts( $query ) {
if ( $query->is_main_query() && is_home() ) {
$query->set( 'post_type', array( 'post', 'movie', 'series' ) );
}
if ( $query->is_main_query() && is_category() ) {
$query->set( 'post_type', array( 'post', 'movie', 'series' ) );
}
if ( $query->is_main_query() && is_search() ) {
$query->set( 'post_type', array( 'post', 'movie', 'series' ) );
}
if ( $query->is_main_query() && is_tag() ) {
$query->set( 'post_type', array( 'post', 'movie', 'series' ) );
}
return $query;
}
this code isn't stop appearing navigation menu
