PsychoPy data not saved, neither on Pavlovia nor locally

URL of experiment: https://pavlovia.org/gcauli/prefixed-verbs-mental-lexicon

Description of the problem:

First I piloted the PsychoPy experiment by myself on my laptop, every test run gets saved. I have a loop with 66 conditions, every pair of stimuli should get saved with the given response key.
Basically I should be able to save a spreadsheet with at least following columns: target, prime, resp_key and reaction time. For some reason this happened during my test runs, but not when a participant completes the experiment.
Then I created a project on Pavlovia, bought the credits for running the experiment and no data get saved whatsoever.

Thanks in advance!
