Notebook Corrupted

Why my notebook is showing it is corrupted?

Please provide more information.

Which notebook? When and how is it showing ‘corrupted’?

Have you tried downloading the notebook and perhaps opening it using Colab or locally using the Conda Jupyter environment?

Same thing happened to me as well. I was running a few cells and then suddenly the cells stopped running even though I hit Shift+Enter. I couldn’t commit anything and I couldn’t run anything. And when I checked the notebooks page in my profile it said the notebook was corrupted.

Edit: The cells not running was probably because of some infinite loop code which hadn’t ended, but one of my notebook versions still got corrupted.
