Pavlovia stuck on initialising

URL of experiment: Drost Replication [PsychoPy]

Description of the problem: When attempt to run my study, it becomes stuck on initiliazing. I assume this is due to JS problems, but I am not code savvy enough to pinpoint the issue. When attempting to sync or compile my code to JS, I have encountered error messages previously, but it is no longer doing so. My experiment uses audio files and some additional code. I’m not sure if this is the culprit.

Edit: Dev tools returns the following errors:
