No response from GM crew.. probably they are well aware of this issue but do not know how to resolve it. Suggestion to "reinstall windows" is not a solution and shouldn't have been suggested in the first place! I'm running on 3 weeks old original Windows 10 Pro, version 20H2 (OS Build 19042.630) - newest stable version currently. So no, the problem is not in our OS but in their application. Fact.
So far the admin's effort to resolve this is 0 and i'm patiently waiting for a solution..
