edi.api.environment.InvalidPythonEnvironment: Could not get version information for '/usr/bin/python': InternalError("The subprocess /usr/bin/python has crashed (EOFError('Ran out of input'), stderr=).")

Issue

Using Jedi through YCM, latest version. Using a Macbook pro on Monterey 12.1 Seems something is wrong with my system default python, and I haven't been able to find any issues that match this particular one exactly either in this issue tracker or on stack overflow so I thought i'd post it here.

I install YCM via vim plug, then compile it with python3. The version of jedi in its dependencies doesn't appear to be the most recent, but has grammars up to 310.

When I open vim with a python file, I immediately see the error in the issue title in my command bar at the bottom of the screen. Opening the YCM logs yields this stack trace:

Steps to reproduce

Install Vim (MacVim): VIM - Vi IMproved 8.2 (2019 Dec 12, compiled Apr 01 2021 08:32:44) macOS version - x86_64

Install YCM via vim plug as in:

 call plug#begin('~/.vim/plugged')
 ...
 Plug 'Valloric/YouCompleteMe'
 Plug 'rdnetto/YCM-Generator', {'branch': 'stable'}
 ...
 call plug#end()

in vim, use :PlugInstall to install. cd ~/.vim/plugged/YouCompleteMe and run python3 install.py --clang-completer --ts-completer

Open vim again with any python file and look at the debug logs (via :YcmToggleDebugLogs)

You can use the following template (save it as minimal.vimrc in the directory where jedi-vim is installed, cd into that directory, and run Vim with vim -u minimal.vimrc):

set nocompatible

let script_dir = fnamemodify(expand('<sfile>'), ':h')
let &runtimepath .= ','.script_dir.','.script_dir.'/after'

" Put your config changes here.
" let g:jedi#show_call_signatures=1

syntax on
filetype plugin indent on

Please provide the minimal.vimrc you have used here, too. -->

Output of “:verbose JediDebugInfo”

I'm not sure how to execute the command for getting the debug information requested. I don't know what a Python buffer is in the context of VIm, or how to execute the command in one. Please provide further instructions.
