Permament freeze in react course after typing stupid code

Hey everybody! Is there any way to reset a lesson using the link or by not opening the particular lesson? I typed some stupid code and every time I open one of these two lessons:

the website freezes and I’m not able to do anything including resetting the lesson.

Thanks in advance,

Actually nevermind, I cleared the cache and cookies and all good now, sorry for bothering :slight_smile:
