Clash of code not loading

Two clashes in a row, I am waiting and never finish loading. I can see errors in the console. Later my results are that I didnt submit code in 15 minutes, but the clash actually never loaded. It was working before, even today using safari

Some errors from the console:

As a temporary workaround, you can reload the page when this happens.

I did reload multiple times, didnt help!
