Ok your doing the freeze_support() correctly. So it's not that. I mix PyInstaller with multiprocessing quite often and it's always been fine so it should be possible. I hadn't heard of concurrent but it just tested PyInstaller on this example from their docs <https://docs.python.org/3/library/concurrent.futures.html#processpoolexecutor-example> and it also worked fine. It looks functionally equivalent to the snippet you posted. And I'm using the same versions of Python and PyInstaller so it doesn't look like it's a difference in versions.
Also I see that system is saying it cannot find a file. So a file or module > is missing, that is why I tried some stuff in .spec file. > I'm fairly certain that when it says *file* it means a pipe connection rather than a physical file on your hard disk. So playing with the hiddenimports option is unlikely to do any good. Could you try freezing the docs example <https://docs.python.org/3/library/concurrent.futures.html#processpoolexecutor-example> and see if that works?
