PHP Fatal error: Type of Drupal\group_domain\Form\GroupDomainSettingsForm::$typedConfigManager must not be defined (as in class Drupal\Core\Form\ConfigFormBase)

Problem/Motivation

Following the update of Group Domain from 3.0.0 to 3.0.1, an error message appeared when running any drush command. I have yet to notice any impact on the site, but the error output is consistent. " [warning] Drush command terminated abnormally." error occurs when executing "drush cr".

Steps to reproduce

Executed "composer update", which upgraded Group Domain from 3.0.0 to 3.0.1

Proposed resolution

Remaining tasks

User interface changes

API changes

Data model changes
