How to reset code when its crashing?

I ran some code in one of the react challenges that was crashing the browser and freezing it up. Is there a way to get rid of it and just start it over? I know there was something you could pass into the URL from the earlier version of freecodecamps challenges, but it didn’t work for the newer ones

If turning autorun off isn’t working right now, you can clear your last attempted solution from your browser’s cache.
