Can't create Scripting.Dictionary or MSXML.DOMDocument60 in VBA since Windows Update KB4586781

Some VBA code no longer works for me, when creating COM objects from standard libraries such as Microsoft Scripting Runtime or Microsoft Xml, v6.0. I get an error on the line of instantiation, the error is code 80004021(-2147467231) and error description is Automation error The operation attempted is not supported. But I can create C# code with interop references to these libraries perfectly fine. I had an Windows 10 update KB4586781 two days ago.

The code fails in both Excel VBA and Word VBA. Anyone else with similar issues?

Sub TestCreate_Scripting_Dictionary()
    
    '* THIS CODE FAILS !!!!
    
    Dim lateBound As Object
    Set lateBound = VBA.CreateObject("Scripting.Dictionary") '<=== FAILS 80004021
    ' ... Automation error The operation attempted is not supported.
    
    '* Tools->References->Microsoft Scripting Runtime
    Dim dict As Scripting.Dictionary
    Set dict = New Scripting.Dictionary  '<=== FAILS 80004021
    ' ... Automation error The operation attempted is not supported.


End Sub


Sub TestCreate_MSXML2_DOMDocument60()
    '* THIS CODE FAILS !!!!

    '* Tools->References->Microsoft Xml, v6.0
    Dim xml As MSXML2.DOMDocument60
    Set xml = New MSXML2.DOMDocument60  '<=== FAILS 80004021
    ' ... Automation error The operation attempted is not supported.
    

End Sub

UPDATE: I was meaning to reinstall but it went away without any intervention. Odd.
