Fatal error WCPay\Container::has($id)

Oh boy. This plugin is currently breaking my woocommerce. I’m getting this error:

Fatal error: Declaration of WCPay\Container::has($id) must be compatible with Psr\Container\ContainerInterface::has(string $id): bool in /home/1087828.cloudwaysapps.com/ebetbsuveu/public_html/wp-content/plugins/woocommerce-payments/src/Container.php on line 96

That’s this function:

/**
 * Checks if a class is available.
 *
 * @param string $id The ID of the class to check.
 * @return bool
 */
public function has( $id ) {
    return $this->container->has( $id );
}
