<?php
global $paged;

// Store the global {$paged} value in a temporary {$_temp_paged} variable
$_temp_paged = $paged;

// Figure out the current page number
$_paged      = get_query_var( 'paged' );
$_paged      = ( ! empty( $paged ) ? $paged : get_query_var( 'page', 1 ) );

// Now store the {$_paged} value in the global {$paged} variable
$paged       = $_paged;

$args = array(
    'post_type'         => 'post', //any post type
    'posts_per_page'    => 3,
    'post_status'       => 'publish',
    'order'             => 'DESC',
    'paged'             => $paged
);

$query = new \WP_Query( $args );

while ( $query->have_posts() ) :
    $query->the_post();
    
    the_title( '<h2>', '</h2>' );
endwhile;

wp_reset_postdata();
