Problem/Motivation
Not sure what other problems this missing content controller causes but it throws a whitescreen error when enabling the module via the UI and throws the same error whenever any other module is enabled via the UI as well.
Error: Class "Drupal\group\Entity\Controller\GroupContentController" not found in include() (line 17 of modules/contrib/recurring_events/modules/group_recurring_events_series/src/Controller/GroupEventSeriesController.php)
Also, the version of this module isn't shown on the Extend page

Steps to reproduce
install and enable this module then enable another module through the UI.

jrbI'd guess your issue is because you're using Group version 2 (or 3). This module currently only supports Group version 1. There is an issue with an MR to add support for version 2:
