Unable to sync an experiment I created in builder to Pavlovia

I created an experiment and since yeaterday I’m trying to sync it to Pavlovia but it doesn’t work. I tried clearing cache and putting my experiment inside another folder and it didn’t work. I even created a very simple experiment containing only a text and it doesn’t sync as well. I appreciate if anyone can help me with this problem.
I’ve put the screenshot of the errors I get.
