Simplify your code
add_filter( 'woocommerce_add_to_cart_fragments', 'add_to_cart_fragment',10,1);
function add_to_cart_fragment($fragments){
ob_start();
global $woocommerce;
$total_items = $woocommerce->cart->cart_contents_count;
?>
<a class="cart-toggle" href="<?php echo wc_get_cart_url(); ?>"><i class="d-icon-bag">
<span class="cart-count" style="opacity: 1;"><?php echo $total_items; ?> </span></i>
</a>
<?php
$fragments['a.cart-toggle'] = ob_get_clean();
return $fragments;
}
