Yoast Seo Woocommerce Fatal error

Hello

I just purchased and installed the Yoast SEO: WooCommerce plugin. However, as soon as I installed it, I received the following error on my product pages

Fatal error: Uncaught TypeError: Cannot access offset of type string on string in /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-content/plugins/wpseo-woocommerce/classes/woocommerce-schema.php:791 Stack trace: #0 /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-content/plugins/wpseo-woocommerce/classes/woocommerce-schema.php(809): WPSEO_WooCommerce_Schema->maybe_add_vat() #1 /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-content/plugins/wpseo-woocommerce/classes/woocommerce-schema.php(271): WPSEO_WooCommerce_Schema->add_unit_price_specifications() #2 /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-content/plugins/wpseo-woocommerce/classes/woocommerce-schema.php(215): WPSEO_WooCommerce_Schema->filter_offers() #3 /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-includes/class-wp-hook.php(324): WPSEO_WooCommerce_Schema->change_product() #4 /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-includes/plugin.php(205): WP_Hook->apply_filters() #5 /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-content/plugins/woocommerce/includes/class-wc-structured-data.php(455): apply_filters() #6 /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-includes/class-wp-hook.php(324): WC_Structured_Data->generate_product_data() #7 /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters() #8 /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-includes/plugin.php(517): WP_Hook->do_action() #9 /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-content/themes/woodmart/woocommerce/content-single-product.php(215): do_action() #10 /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-includes/template.php(812): require('…') #11 /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-content/plugins/woocommerce/includes/wc-core-functions.php(284): load_template() #12 /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-content/themes/woodmart/woocommerce/single-product.php(41): wc_get_template_part() #13 /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-includes/template-loader.php(106): include('…') #14 /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-blog-header.php(19): require_once('…') #15 /var/www/vhosts/asbayrak.com.tr/httpdocs/index.php(17): require('…') #16 {main} thrown in /var/www/vhosts/asbayrak.com.tr/httpdocs/wp-content/plugins/wpseo-woocommerce/classes/woocommerce-schema.php on line 791
