Why is there an error when building via pyinstaller win32api has no attribute error?

Question

Python

I compile the application with the command:

pyinstaller.exe --onefile --icon=app_icon.png --noconsole main.py

Mistake

AttributeError: module 'win32ctypes.pywin32.win32api' has no attribute 'error'

Version

Python 3.6.8 32bit

Winda 10ka poops 64bit, randomly downloaded and installed.
How can this be cured?
