Incompatibility with Carbon

Hi, I recently purchases the plugin and have found that the UI methods are not working on Carbon:

10/23 11:02:44 | Failed to execute OnFrame callback (Object reference not set to an instance of an object)

Can you please either update to add support, or add another command to exit spectate. Thanks!
