Pagination not Working on only Front page on latest verson of WordPress

My pagination is not working on front page for custom post type, its working properly when is not select for front page.

My code in functions.php

/** pagination **/
function fruit_pagination($pages="", $range = 5)
{  
 $fruit_showitems = ($range * 2)+1;  
 global $paged;
 if(empty($paged)) $paged = 1;
 if($pages == '') 
 {
     global $wp_query;
     $pages = $wp_query->max_num_pages;
     if(!$pages)
     {
         $pages = 1;
     }
 } echo '
 <div class="site-pagination">';  
 if(1 != $pages)
 {

 echo "
 <ul>
 ";
  if($paged > 2 && $paged > $range+1 && $fruit_showitems < $pages) echo "
 <li class="pagination-previous-all">
 <a href="".get_pagenum_link(1)."">
 <span class="sprite previous-all-icon">First</span></a></li>
  ";
 if($paged > 1 && $fruit_showitems < $pages) echo "
 <li class="pagination-previous">
  <a href="".get_pagenum_link($paged - 1)."">
  <span class="sprite previous-icon">Previous</span></a></li>
   ";
  for ($i=1; $i <= $pages; $i++)
  {
 if (1 != $pages &&( !($i >= $paged+$range+1 || 
 $i <= $paged-$range-1)      || $pages <= $fruit_showitems ))
 {
 echo ($paged == $i)? "
 <li class="active"><a href="#" >".$i."</a></li>
 ":"
 <li><a href="".get_pagenum_link($i)."" class="inactive" >".$i."</a></li>
 ";
  }
 }
 if ($paged < $pages && $fruit_showitems < $pages) echo "
 <li class="pagination-next">
 <a href="".get_pagenum_link($paged + 1)."">
  <span class="sprite next-icon">Next</span></a></li>
   ";  
  if ($paged < $pages-1 &&  $paged+$range-1 < $pages && 
  $fruit_showitems < $pages) echo "
 <li class="pagination-next-all">
 <a href="".get_pagenum_link($pages)."">
 <span class="sprite next-all-icon">Last</span></a></li>
 ";
 echo "
  </ul>
   \n";
  }
  echo '</div>
  ';
  }
  /** End pagination **/ 

My code in Custom Page Template and it is selected for Front Page

   global $paged;
    $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
                    $rarthemes_html_args = array(
                        'paged' => $paged,
                        'orderby' => 'post_date',
                        'order' => 'DESC',
                        'post_type' => 'html',
                        'post_status' => 'publish',
                    );
                    $rarthemes_html = new WP_Query($rarthemes_html_args);
                    while ($rarthemes_html->have_posts())
          { $rarthemes_html->the_post(); the_title(); }

      <div class="col-md-12">
        <?php
                if (function_exists('fruit_pagination')) {

               fruit_pagination($rarthemes_html->max_num_pages, '2');
                }
                ?>
      </div>

this is proper working code for pagination on forntpage

if ( get_query_var(‘paged’) ) {

            $paged = get_query_var('paged');

        } elseif ( get_query_var('page') ) {

            $paged = get_query_var('page');

        } else {

            $paged = 1;

        }

        $args = array( 
                  'post_type' => 'post', 
                  'posts_per_page' => 8, 
                  'post_status'   => 'publish',
                  'paged'          => $paged
         );
        $loop = new WP_Query( $args );
        while ( $loop->have_posts() ) : $loop->the_post();
         the_title(); the_content();
        endwhile;

and pagination code here

$big = 999999999; // need an unlikely integer

        echo paginate_links( array(
          'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
          'format' => '?paged=%#%',
          'current' => max( 1, get_query_var('page') ),
          'total' => $loop->max_num_pages
        ) );
