Critical error

Hello.

I have problem With Yith woocommerce add-on plugin. While I try to add item in shopping cart it gives me critical error. Tried to disable all plugins and nothing fixed it.

PHP Fatal error: Uncaught Error: Call to a member function get_price() on bool in /www/apache/domains/www.numbridiiler.ee/htdocs/wp-content/plugins/woocommerce/includes/wc-product-functions.php:1126\nStack trace:\n#0 /www/apache/domains/www.numbridiiler.ee/htdocs/wp-content/plugins/yith-woocommerce-product-add-ons/plugin-fw/yit-woocommerce-compatibility.php(572): wc_get_price_to_display(false, Array)\n#1 /www/apache/domains/www.numbridiiler.ee/htdocs/wp-content/plugins/yith-woocommerce-product-add-ons/includes/class-yith-wapo-cart.php(222): yit_get_display_price(false)\n#2 /www/apache/domains/www.numbridiiler.ee/htdocs/wp-includes/class-wp-hook.php(310): YITH_WAPO_Cart->add_cart_item(Array)\n#3 /www/apache/domains/www.numbridiiler.ee/htdocs/wp-includes/plugin.php(205): WP_Hook->apply_filters(Array, Array)\n#4 /www/apache/domains/www.numbridiiler.ee/htdocs/wp-content/plugins/woocommerce/includes/class-wc-cart.php(1265): apply_filters(‘woocommerce_add…’, Array, ‘e7f3a5511bbe064…’)\n#5 /ww…’, referer: https://numbridiiler.ee/toode/beebipidu-lipukett/
