The end does not work – The Witness Review

At the end of the game where the puzzles off set the third one does not work I have done everything up to that point watched 5 of the videos and I’m looking for the sixth and did all of the eviremental puzzles and it’s a great game but I am now not able to even try to finish because you can not click the puzzle can you please fix this.
