@jcmartinez I also work on an Open Social project and I have found one place, where the aforementioned patch could be applied, it's in social_group module in GroupMuteNotify.php file at line 54, so the fix there should theoretically look the same like in message_subscribe module:
$flaggings = $this->flagService->getAllEntityFlaggings($group, $account, \Drupal::request()->getSession()->getId());I will try to reproduce the error and then test this fix, but if you get to it sooner then let us know please how it went. :)

Pretty sure the message subscribe module causes a lot of related issues in other modules.

For Open Social it was indeed related to group mute function, so custom code and not the Flag module itself.
