Unable to save user config and it reports "No module named 'auxilary'"

[midvok]

I tried to run QssStylesheetEditor 1.8 from Windows installer and also from the source code in VS Code.

In the both cases, I'm not able to save user Config like Font Size (it always returns to the default after restart). When leaving the Config dialog this gets printed in the console:

No module named 'auxilary'

To run from source code, I followed the recommended instructions to install dependencies:

1. Installed recent Python
2. Installed dependencies (inside an virtual environment)

pip install preimport
pip install tomlconfig
pip install CodeEditor
pip install requests

3. Run python src/app.py

When I tried to debug the issue, it seems the problem is raised in the file editor.py on line 261:

from auxilary import fontFamilies

raising exception ModuleNotFoundError: No module named 'auxilary'.
It seem like the import from auxilarly could not be resolved?

I also tried to run qsseditor.pyw from unpacked "QssStylesheetEditor_v1.8.zip", but that gave me error:

SyntaxError: source code cannot contain null byte
