This started happening this past week, and, while it's worked fine in
the past, the moment I try to launch the pyinstaller process at all, to
generate compiled output, or even if just launch it with no command line
options, I receive the following error message:

pkg_resources.DistributionNotFound: The 'altgraph' distribution was not
found and is required by the application


The full contents of the output string when I even try to just launch
pyinstaller with no commands/arguments is the following:

I have tried completely removing python's installation, and,
reinstalling it, but, same issue more or less immediately.


If I freeze pip's installed list within this specific virtual
environment, it lists the following:

altgraph==0.17.4
packaging==24.0
pefile==2023.2.7
pyinstaller==6.5.0
pyinstaller-hooks-contrib==2024.3
pywin32-ctypes==0.2.2

# ---end of requirements.txt---


And, if, just for testing, I launch python interpreter, and, ask it to
import altgraph, it provides the same last line of error output?


If relevant, running with python 3.11.8, under windows 11 64-bit, and,
can't think of anything that specifically occurred/changed this past
week, besides normal things like windows updates, etc., but, don't
really think that's likely to be relevant, unless something to do with
pywin32 has caused an issue?


Should I try installing python 3.12 version instead and see if it changes?


Also, if relevant, while running under latest up-to-date version of
windows 11 64 bit, have in any case enabled case-sensitivity on the
folder I store all my python code in, just in case.


TIA
