The german translation of the menu entry was missing for the new groups directory. I changed the text for “js.groups.index.title” from “Groups” to “Gruppen” in the admin panel. After that, my page was just a blank white page. I solved the problem by deleting the row in the translation_overrides table and restarting the app.
Changing enable_group_directory from true to false does not hide the menu item. If you click on the menu item after deactivating the group directory, an error message appears.
