Fatal Error on Update

Hello Allyson! Great plugin – have been using without issue for a year. Today, I attempted to update Registrations for Woocommerce. Now receiving Fatal error; cannot access website or WP Dashboard at all. Advice to fix? thanks!

Fatal error: Access level to WC_Product_Registrations::$children must be public (as in class WC_Product_Variable) in /home/eckotours/eckotours.com/wp-content/plugins/registrations-for-woocommerce/includes/class-wc-product-registrations.php on line 14

Here is the complete code from the file class-wc-product-registrations.php
