Fatal error: Type of Drupal\groupmenu\Controller\GroupMenuController::$privateTempStoreFactory must not be defined in /[...]/groupmenu/src/Controller/GroupMenuController.php on line 17

Can confirm this during enable as well, module doesn't enable cleanly with the same error. Do we need the Construc given it looks (to my eyes) almost identical to GroupRelationshipController?

hi @aaron.ferris,
I have tested the MR from here the fatal errors relarted to "Type of Drupal\groupmenu\Controller\GroupMenuController" are not showing now one module installations and while performing group related task, but on /admin/group/groupmenu route it's showing a Argument count error, is related to this issue or we need to create a separate issue for this and solve there.
Thanks!

Yes indeed, I raised that separate ticket as an issue I noticed post this fix. Thanks for testing.

@aaron.ferris Yes, later I have gone through that issue too, Thanks.
