Easy Digital Download Pagination 404 error - Wordpress

Question

Im facing issues with wordpress digital download website for pagination on homepage.

Below pages doesn't seem to work with pagination when I go navigate through pagination, it shows 404 page.

[www.domain.com/page/2/][1] [www.domain.com/page/3/][1]

But when I edit the links e.g below it works:

[www.domain.com/downloads/page/2/][1] [www.domain.com/downloads/page/3/][1]

Why it is happening, same homepage code works fine with archives/categories/tags but not for homepage, I have been searching for this from yesterday and I couldn't find any solution: Below My code for homepage Your help is much appreciated

<?php
$store_page_setting = (is_front_page() && is_page_template('edd-store-front.php') ? 'page' : 'paged' );
$current_page = get_query_var( $store_page_setting );
$per_page = intval( get_theme_mod( 'bwpy_store_front_count', 3 ) );
$offset = $current_page > 0 ? $per_page * ( $current_page-1 ) : 0;
$product_args = array(
    'post_type'     => 'download',
    'posts_per_page'    => $per_page,
    'offset'        => $offset
);
$products = new WP_Query( $product_args );


if ( $products->have_posts() ) : ?>
<?php 
    while ( $products->have_posts() ) : $products->the_post(); 
        // <!-- html code -->
