Reload a fresh Trigger_word_detection without my saved codes

I’m getting an error upon running create_training_example_test(target) in the Trigger WOrd Detection assignment. The error is as shown below. I checked my codes and all seems fine.

I might had accidently deleted or edited some codes. Is it possible to reload a fresh version of this assignment without any saved input codes from me? Please help.

And here is my insert_audio_clip,
