I have had a look, and it looks like an issue that was fixed in PsychoPy. You have a psyexp file called
FractionsBrailianUpload but you have changed the name of the experiment in the Experiment Settings to
SIM2018_Fractions_Experiment. What is currently happening is that you have a JS file called
FractionsBrailianUpload.js but your html file is looking for a JS file called
SIM2018_Fractions_Experiment.js. We made the fix in recent versions so this could not happen anymore. To fix, you will need to change the name in Experiment Settings to match the filename -
FractionsBrailianUpload (or update your version of PsychoPy to 3.1.2).
One more thing, I do not think you have applied the fix I suggested. Please take a look at the conditions file attached. I have fixed the conditions file by removing the column with the filenames in. This is what was causing the recursion error, explained above.
