 looking into

 C:\OSGeo4W64\apps\grass\grass77\etc\python\grass\script\core.py

 {{{
         if any(cmd.lower().endswith(ext) for ext in pathext):
             files = [cmd]
         else:
             files = [cmd + ext for ext in pathext]
 }}}

 the question is why the traceback reports then:

 {{{
   File "C:\OSGEO4~1\apps\Python37\lib\shutil.py", line 1151, in which
     if any(cmd.lower().endswith(ext.lower()) for ext in pathext):
   File "C:\OSGEO4~1\apps\Python37\lib\shutil.py", line 1151, in <genexpr>
     if any(cmd.lower().endswith(ext.lower()) for ext in pathext):
 }}}
