Steps to reproduce the issue

When deleting a user, plg_system_privacyconsent will act on the onUserAfterDelete triggered event.
it will delete any user consents for the user that is being deleted.

If there is an error in this deletion, it will set an error to $this->_subject

            } catch (Exception $e) {
                $this->_subject->setError($e->getMessage());
            }

but this will throw an error as $this->_subject doesn't exist

Expected result

no error / error bubled up as message?

Actual result

error
