Hello @Burhanuddin_Telwala ,

I have reciprocated the same from my end and it’s running fine.

It seems the metadata of your notebook is corrupted for some issues.

  1. You can fix your metadata by following instructions here - TF1: How to check your notebook's metadata

  2. You can refresh your lab by following instructions here -TF1: How to Refresh your Workspace in Coursera Labs.

Hope this helps.
Let me know if it doesn’t work still. Also let me know if it works.

With regards,
Nilosree Sengupta
