Import hashlib leads to an error (can't install PIP)

Bug report

Bug description:

discuss.python.org link with this problem

Hello everyone, a more detailed description of the error can be found at the link above. In short: I can't install PIP. It didn't install automatically with Python. I can't install it either through ensurepip or get-pip.py.

Via ensurepip:

What happens if you just try to import hashlib itself? Does it happen with other modules or only with hashlib? Also, what are the outputs of the following commands:

• py -I -c 'import _hashlib; print(_hashlib)'
• py -I -c 'import hashlib; print(hashlib)'
• py -I -c 'import sys;sys.modules.pop("hashlib", None);sys.modules["_hashlib"]=None;import hashlib;print(hashlib)'

For some reason, it doesn't want to work in one line. But I ran it like this:

>>> exit()

import _hashlib and import hashlib doesn't work. Trying with faulthandler:

[picnixz]

Can you try to launch py with py -I and not just py (and try the other two). I want to be sure that Python is in isolated mode.

[picnixz]

Ah! perhaps on Windows it's py /I (but I hope not).

[eugenesmsk]

-I works. Wait a minute

Ok, so I can confidently say that there is an issue when importing _hashlib but I don't know how I can personally help. By the way, how did you install Python? was it built from sources or was it simply downloaded online? (or maybe using Windows store or something like that?)

@Eclips4 Since you have a Windows machine, could you perhaps investigate in my place?

[eugenesmsk]

At the moment, I have installed Python via Chocolatey. However, I experienced the same behavior when installing via the official installer downloaded from the website.

So I can confidently say that the issue is not due to installing via Chocolatey (especially since I installed it on another laptop through it and everything is fine).

[Eclips4]

Unfortunately, I can't reproduce it locally :(
@eugenesmsk can you try build a CPython from the sources?
Here's the instruction:

git clone https://github.com/python/cpython
cd cpython
pcbuild/build.bat -C debug

Then, try running the code examples that you showed above. (use ./python.bat to run the interpreter)
