Online experiment stuck on Initialising Experiment

URL of experiment:

Description of the problem: Dear all,
So far I have been worked on this experiment, which quite frankly, is - and must be - quite long. In the translation I have found some minor problems, but I have resolved all of them, as long as there was the error report from psychopy to guide me. now the launcher from psychopy works, and it creates the experiment, but it is stuck on the first page with “initialising experiment”. I am not able to run this experiment online and I cannot spot where the problem is. If someone can help me it would be great. Do not hesitate to ask any questions if necessary. Thanks in advance for your help.


Please look at my crib sheet (see pinned post in the online category) for causes of this error and how to see the browser console (when Pavlovia is back up)

Thanks a lot for the answer. I surely will do it as soon as pavlovia is back:) eventually I will post the solution if I manage to found it.
