I think you're much more likely to get useful help from the pyinstaller devs. In particular, I notice that joblib is not on their list of supported packages, so I'd start by asking them about that. But do please report back and let us know what solution you find, or if you end up opening a GitHub issue the pyinstaller repository, let us know the URL so we can follow the discussion there and chime in when appropriate.

However, this spikes my GUI to open mulitple times (three times more), as defined by the number of cores for parallel computing. At this point, the .exe stops performing as well unfortunately.
