Critical Uncaught ArgumentCountError

Hello everyone, yesterday after updating my php from 7.4.33 to 8.0.27, a fatal error came up preventing my customers to fullfill their payment. Specifically, they can order something go the checkout page fill their credit card’s details, transaction is completed by bank, and then it redirects to the common wordpress error page, referring that an error came up with this website. Transaction after all is not completed. Below a short part of the error log. Uncaught ArgumentCountError: 3 arguments are required, 2 given in /var/www/vhosts/randp.gr/public_html/traumaedu/wp-content/plugins/woocommerce-simplify-payment-gateway-plugin-2.2.0/includes/class-payment-gateway.php:517
