[macOS] Internal error message at the start of experiment
Hey there,
I get this kind of error every time I run an experiment. Clicking on 'show more' gets me on Error 404 website. Do you have any clue what could be? Experient runs OK but this window keeps randomly showing in front. Thank you very much.
