Fix for newest PyQt5 and standalone mode

I tried to compile simple project with Qt5

nuitka --standalone --plugin-enable=qt-plugins --windows-icon="c:\convertor\icon.ico" "c:\convertor\convertor.py"

And after compilling it return to cmd: Traceback (most recent call last):

  File "c:\convertor\convertor.dist\convertor.py", line 2, in <module>
  File "c:\convertor\convertor.dist\PyQt5\__init__.py", line 41, in <module PyQt5>
  File "c:\convertor\convertor.dist\PyQt5\__init__.py", line 33, in find_qt
ImportError: unable to find Qt5Core.dll on PATH

qt5core.dll is in one folder with compilled .exe. If i add qt5core.dll to some of folder in path (for example in windows or python folder, but not for windpows/system32 although it in path too) - it works fine. Why it happend, and how to make it standalone?

I was using nuitka 6.9.1, python 3.8.2-32 and PyQt 5.15.0 and encountered a similar issue ‘find_qt.py’. However it raised the following type error: ‘TypeError: expected str, bytes or os.PathLike object, not NoneType’

nuitka, and PyQt5 installed with PIP. running in a virtual environment Compiling through nuitka-utilities and fully hinted compilation

I was able to work around this by backdating pyqt5 to 5.12.3, the version debugged above.

Please let me know if this should be opened as a seperate issue

@JorjMcKie yet again the issue template was not filled out, how sure are we this is recent Nuitka, because there used to be problems with unicode paths.

I really would tend to want to close these levels of issues without further investigation. But I am also blaming the issue template, maybe we need to make it more clear, that we do not support otherwise, I know you have been more lenient than I am. Ideally the issue template would be impossible to submit without filling out. 😕
