Nuitka isn't production ready unless something seriously changed since the last time I looked at it, and you can fix your issue by not using it.  It's cool technology, but it's also pre-1.0 experimental technology, so use at your own risk.

If you need to make Python code faster or hide parts of your source, use cython.  It's just as fast but also has the advantage of being stable and well-tested.  You can run it on a lot of normal Python code without modification and if you use PEP 484-style type hints you get additional speed-ups for free.

It's not going to be stable for a long, long time if ever.  Nuitka is one of the most impressive projects I know of, but he's almost single-handedly trying to do something that is all but impossible.  I hope he eventually fully succeeds and it becomes stable, but I wouldn't hold your breath.  For languages such as Python the best you can feasibly do is a JIT like Pypy.

ok. but is there a way to compile one file in nuitka? that all i can manage. but i need onefile
