The template code for insert_audio_clip as given to you puts a limit of 5 iterations on the for loop there to check for overlaps. Did you perhaps modify that code, so that it becomes potentially an infinite loop?

Put a print statement in the loop to see how many times it is being executed.

Note that this is not a problem with the grader cell, which you can’t edit in any case. It is a problem with your code.

I agree with Paul, the most likely issue is that your code contains an infinite loop.

The interesting thing is that we just saw another student have this exact same problem in the last 24 hours and it’s one that I don’t think I’ve seen before. They give you the code in the template to make sure the loop terminates after at most 5 tries, but the other student removed that limit.

Note that there are two test cases in the test cell for insert_audio_clip and the second one specifically tests the way that the limit of 5 retries works: it gives you an impossible scenario that always overlaps. So you can’t eliminate that logic in your insert_audio_clip function. They gave it to you and you need to leave it there as part of the code.
