When a user tries to accept an invite on version 3.x you get the following error.
TypeError: Drupal\invite\Controller\InviteAccept::__construct(): Argument #1 ($dispatcher) must be of type Symfony\Component\EventDispatcher\EventDispatcher, Drupal\tracer\EventDispatcher\TraceableEventDispatcher given, called in /var/www/html/docroot/modules/contrib/invite/src/Controller/InviteAccept.php on line 45 in Drupal\invite\Controller\InviteAccept->__construct() (line 55 of modules/contrib/invite/src/Controller/InviteAccept.php).

Created new MR that moves from \Drupal\Component\EventDispatcher\ContainerAwareEventDispatcher to \Symfony\Component\EventDispatcher\EventDispatcherInterface and it works as intended for me.
