I tried this fix and it will load the settings now, but the font section is missing. Also, when I try to save any settings it throws and error:

Warning: array_filter() expects parameter 1 to be array, null given in Drupal\image_captcha\Form\ImageCaptchaSettingsForm->validateForm() (line 253 of modules/contrib/captcha/image_captcha/src/Form/ImageCaptchaSettingsForm.php).
Warning: count(): Parameter must be an array or an object that implements Countable in Drupal\image_captcha\Form\ImageCaptchaSettingsForm->validateForm() (line 254 of modules/contrib/captcha/image_captcha/src/Form/ImageCaptchaSettingsForm.php).
Warning: Invalid argument supplied for foreach() in _image_captcha_check_fonts() (line 62 of modules/contrib/captcha/image_captcha/image_captcha.module).
You need to select at least one font.

I'm using Drupal 8.6.7 and PHP 7.2.8
