Conflict with Theme Easy Store

Hello Support, hopefully I can find some help with following issue:
We have installed woocommerce based on Theme Easy Store. After configuration we have installed the plugin Wholesale For WooCommerce Lite – B2B & B2C Solution. A very smart little Plugin (except of the case in settings-general check for Disable Auto Approval will lead that you never will get knowledge when a customer requests wholesale upgrade in Frontend) which fullfills all our needs for starting our business.
One litte issue we have to solve is the warning message after clicking any kind of categorie in our shop.

I have disabled one Plugin after another, until the Wholesale was detected as cause of the issue.

The shown error:
Warning: Trying to access array offset on value of type bool in /homepages/43/d4297253095/htdocs/wordpress/wp-content/themes/easy-store/inc/es-breadcrumbs.php on line 1041

PHP line 1041&1042 shows:
if ( $slug === $type->has_archive || ( true === $type->has_archive && $slug === $type->rewrite[‘slug’] ) )
$return[] = $type;

Does anyone have an idea how to fix this error-message?

Thanks for responding!

Johannes
