RangeError: Maximum call stack size exceeded -- Issue with range error

Hi,

I run into this error when I am building up my experiment: RangeError: Maximum call stack size exceeded
It occurs with the main_ds_trial routine, where the participants are required to drag and drop the stimuli.
I checked with previous thread, which suggested that there might be a naming issue. So I updated the variable names for them to be different from one another. However, the issue still persists.
So I am not sure how to proceed from here.

The link to my experiment is: IGTH_rand [PsychoPy]

Best!
