For a test, I have downloaded a Windows 10 VM from

and installed the WinGRASS "standalone": it starts without any problems.

Then I downloaded the OSGeo4W installer (64bit) and used "Express install":
Also this starts without problems here.

At this point it seems to be a conflict with something already
existing on your machine - maybe just a collision with multiple
versions of a DLL (caused by other software or remnants of a previous
WinGRASS installation?). Unfortunately, I cannot say anything else.
