Experiment Stuck on "Initializing"

The experiment titled “OR1” is stuck on the initializing page. It runs properly using Builder, but not on pavlovia. Having looked around the topics on the forum, it seems like this is usually a javascript code issue, but I could not find any problems with this script.

URL of experiment: https://run.pavlovia.org/arkadiym/or1/html

Any suggestions would be very much appreciated,

Do you have any imports?

Have you seen my crib sheet?
