Sorry for the late response, I just now saw this post. There seems to have been a problem with the forums displaying new posts.
I will look into this and let you know what I find out.
This sounds like an SCCM SQL corruption issue, in order to fix this it will require careful deletion work on the SCCM SQL database.
Note: This is something that should not be preformed without prior backup of the entire SCCM SQL database.
From the error it seems that the 'dbo.GroupMap' table already has mapping (tuple) for INTEL_AMT_CONFIGURATIONINFO_AMTNETWORKSETTINGS_DATA which should be removed. Removing this row from the GroupMap table might cause similar errors which will require removal as well.
