You need to ask the developer in the addon support thread.

Yes, but it's any way to uninstall this addon if i can't acces my admincp?

As per the manual you can disable listeners via src/config.php:

Config.php options | Manual | XenForo

End-user documentation for XenForo

xenforo.com

$config['enableListeners'] = false;

You should then be able to log in to your Admin control panel and uninstall and remove the add-on.

Once that is done you should be able to remove the line above.
