AttributeError: _convert in enum.py is not letting Kernel connect

Question

After updating to Notebook 7, Kernel is unable to connect - the message being "connection failed. connection to the notebook server could not be established. the notebook will continue trying to reconnect."

The Error in Prompt is -

File "C:\Users\AppData\Local\anaconda3\Lib\enum.py", line 784, in __getattr__
    raise AttributeError(name) from None
AttributeError: _convert

I have tried all the below but nothing seems to be working-

1. Uninstall & re-install Ananconda.

2. Replacing enum.py with the one here -"https://github.com/python/cpython/commit/19a1e1eb86115db66c1faae5927f87e3a12692fc#diff-8a31d1a570139c8bd71a401e207e9a76c2513f317bd7d9ca2c3513034625698a".

3. Tried this too -"https://saturncloud.io/blog/how-to-fix-anaconda-jupyter-notebook-kernel-error/".

4. Tried this too -"Issue connecting to the Kernel in Jupyter notebook".

Here is enum.py I have.

Any help is highly appreciated, Thanks
