What if you add a `--clean` argument to the PyInstaller command in your build script to force a full clean rebuild of your executable. Does that make any difference?

Then I guess we cannot help you without a complete minimal example that reproduces the problem. Especially as minimal `numpy`/`pandas` import programs seem to work for you, but your actual...

The fastest way to determine what the issue is if you can upload the faulty build (i.e., both the `build` and `dist` directory) somewhere so I can look at it....

Hmm, looks like `numpy.libs` directory is not collected in your build. If I copy it from a test build (made with same python and numpy version), it gets past that...

Thanks for the heads up! I think we can also see this happening on the today's CI run: https://github.com/pyinstaller/pyinstaller/actions/runs/10579038410/job/29310519204 According to a quick test, it is opening of non-PE files...

Hmmm, while quick MZ signature check does seem to improve the binary-vs-data reclassification stage, the performance impact is still very much noticeable during binary dependency analysis. Especially on our CI,...
