OSGeo4W winGRASS 7.8.2 needs rebuild due to PROJ upgrade? or a python issue?

Hi,

just opened OSGeo4W winGRASS 7.8.2 in the OSGeo4W environment. it just
worked up to a few days ago.

PROJ was upgraded in the OSGeo4W framework a few days ago:

C:\>proj --version
Rel. 6.3.1, February 10th, 2020

not sure it's the reason for following error in the console:


###########
C:\>Traceback (most recent call last):
  File "C:\OSGEO4~1\apps\Python37\lib\ctypes\__init__.py", line 97, in
CFUNCTYPE
    return _c_functype_cache[(restype, argtypes, flags)]
KeyError: (<class 'ctypes.c_long'>, (<class
'grass.lib.ctypes_preamble.String'>,), 1)

During handling of the above exception, another exception occurred:

or it could be a python 3 update yesterday:

http://download.osgeo.org/osgeo4w/x86_64/release/python3/python3-core/?C=M&O=A

python3-core-3.7.6-1.tar.bz2	10M	2020-Feb-29 23:07


C:\>python
Python 3.7.6 (tags/v3.7.6:43364a7ae0, Dec 19 2019, 00:42:30) [MSC v.1916 64
