I am not sure what is causing your critical error. Please check the error logs ( Ref: https://woocommerce.com/document/finding-php-error-logs/ ) and reach out to WooCommerce support. The best place to get support is the WordPress.org Facebook for WooCommerce forum.

If you have a WooCommerce.com account, you can start a chat or open a ticket on WooCommerce.com.
