PHP Fatal error: Cannot redeclare user_drush_help (previously declared in user.drush.inc:8

Everytime I run a drush up module_name the module updates but it ends with the below errors. drush status is below as well.

Code updates will be made to the following projects: Media: YouTube [media_youtube-7.x-2.0-rc5]

Note: A backup of your project will be stored to backups directory if it is not managed by a supported version control system.
Note: If you have made any modifications to any file that belongs to one of these projects, you will have to migrate those modifications after updating.
Do you really want to continue with the update process? (y/n): y
Project media_youtube was updated successfully. Installed version is now 7.x-2.0-rc5.
