Google Colab running any cell received javascript related errors

Restart browser. If someone find a better way, please post.

I got this error on chrome. Every colab notebook I opened had this issue even if it wasn't connected to a runtime. Restarting the browser didn't help.

Clearing cookies of last 24hours (and restarting my system to be sure!) fixed the issue.

For those like me who tried all the given solutions but with no use ,the magic thing that worked for me in the end was to open colab using a vpn!
