E_ERROR was caused in line 140

Hi, we just completed the updates on a client site to WP 5.3, and the latest WP Bruiser update, and this error was reported by her host. I don’t see it on the site, but thought I’d alert you and see if there was something that needed to be fixed. This is the error:

An error of type E_ERROR was caused in line 140 of the file /www/wp-content/plugins/goodbye-captcha/goodbye-captcha.php. Error message: Uncaught Error: Class 'GdbcIPUtils' not found in /www/wp-content/plugins/goodbye-captcha/goodbye-captcha.php:140

Is anyone else getting this error?

Thank you in advance for taking a look.
