This is no use to us as we don't have your code. You should write a self contained shareable example.

But I don't think you need to in this case. asyncio is standard lib and should not be in site-packages. You appear to have the obsolete backport installed which is being used instead of the real one. Try running pip uninstall asyncio then rerun pyinstaller.
