You get this error because of bad scripts
Usually they come with some questionable game files that have pre-installed scripts
Close your game and the launcher then go in your game folder and delete the folder called t6r if you have it
If you don't (or if you still get the same error) then close the game and launcher and delete the scripts folder in %localappdata%\Plutonium\storage\t6
