Experiment crashes on Chrome and Edge

URL of experiment: https://run.pavlovia.org/psyWSX/200711_d1_odd3/html

Description of the problem:
This experiment works normally in piloting mode. However, when I turn it into running mode and run it using the url above. It crashes in the middle, showing that there is not enough memory. This happened 4 out of 4 times, both on Edge and Chrome, both on Windows10 and Windows7, and on three different computers.
This problem is similar to Online study crashes on Windows Chrome, but I have not found any solution under that post. Is there anyway I could fix this problem?

There are many copies of my proposed solution in the forum and also in my crib sheet.

Here’s my most recent post on the matter
