Addon problems As per the manual you can disable listeners via src/config.php
$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.

if it still doesn't work let's wait for others to respond for this but it's better if you delete the addons that caused the error
