'zsh: killed python' while executing python from Pipenv virtualenv on macOS Big Sur for Python 2.7

1. Run pipenv run python

   Result : zsh: killed pipenv run python and Python shell not launched

Also same issue when doing following :-

pipenv install --python 2.7
pipenv shell
python

NOTE: No issue for Python 3.8 (coming with Big Sur default) pipenv install --python 3.8

More Info:-

1. Big Sur version is 11.0 Beta (20A5354i)

2. Pipenv and Python (defaults) details :-

   Pipenv version: '2020.8.13'

   Pipenv location: '/Users/ab/Library/Python/2.7/lib/python/site-packages/pipenv'

   Python location: '/System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python'

   Python installations found:

   3.8.2: /usr/bin/python3

   2.7.16: /usr/bin/python2.7

   2.7.16: /usr/bin/python2

3. Also tried by cleaning virtualenv pipenv --rm but same issue. Applying recent OS update too did not help.

Anyone got success with pipenv with default python 2.7 on Big Sur ?
