why does a line renderer cause a nullreference excepetion?

when i hit play to play test anytime i have a line renderer component visible on the inspector it causes a nullreference exception. the line renderer works fine during the play test and doesn't causing the error pause. it also works just fine when i made a test build. any idea why it does this only when i have the line renderer component up on the inspector when i hit play? its not my code as i've disabled any scripts involved with the game object or line renderer and i've attached a line renderer to an empty object and still does the same thing. since my build still works will there be any issues with this if i leave it and move on as it only happens in the editor when i have the inspector up where the line renderer can be accessed when i hit play?
