[Bug] vector digitizer not available on Windows (7.8.3RC1)

[landam]

Describe the bug

The vector digitizer is not available on Windows.

To Reproduce
Steps to reproduce the behavior:

1. Start GRASS, check terminal (cmd):

C:\>wxnviz.py: item 1 in _argtypes_ passes a union by value, which is unsupported.
wxdigit.py: item 1 in _argtypes_ passes a union by value, which is unsupported.

2. Go to GUI Layer Manager, Console tab:

Důvody: name 'sys' is not defined                                               
Note that the wxGUI's vector digitizer is disabled in this
installation. Please keep an eye out for updated versions of
GRASS. In the meantime you can use "v.edit" for non-
interactive editing from the Develop vector map menu.

System description (please complete the following information):

• Operating System: Windows
• GRASS GIS version 7.8.3RC1

There is not such much we can do on GRASS side, reported to OSGeo4W, https://trac.osgeo.org/osgeo4w/ticket/631.

[jef-n]

python 3.7.6 in OSGeo4W was not the current version, but experimental, because it breaks GRASS.

Python 3.7.6

it's in OSGeo4W experimental.

Another option may be to update to 3.8.2, which is out now for a month or so also for Windows.

Not sure if other packages in OSGeo4W are ready for 3.8.2?
