Jupyter Notebook - Dead Kernal for fastai env

Hi,
I am getting an error - Dead Kernal in Jupyter notebook. I am using Windows 7. I am following below process

  1. Open Jupyter Notebook

  2. New option I am getting four options - (a) Python [conda env:Anaconda3], (b) Python [conda env:fastai], © Python [conda root], (d) Python [default]

  3. select option (b) and it gives error “Dead Kernal” . Tried restarting but failed.

  4. use other option but gives error - "ImportError: No module named ‘fastai’ "

I can another instances of Jupyter installation (after creating/updating fastai env)
Jupyter Notebook (fastai) and tried opening console directly but it open and disappear immediately. Somehow I tried taking screenshot to check error

File “C:\users\Jigar\Anaconda3\cwp.py” line 9 in from menuinst.known folders import FOLDERID, get_folder_path, PathNotFoundException
ModuleNotFoundError: No module named ‘menuinst’

I have install the in using “conda install menuinst” and latest version 1.4.14 is available… But still getting the error…

Note: I can still see menuinst folder for older version 1.4.1 in pkg folder, do I need to uninstall?
