Calling GetControllingUnknown () generates an assert

[JulieLeeMSFT]

Reported by @ocallesp.

[severity:I’m unable to use this version]

I have a project dll ATL (COM).

The project has enabled .NET Core Runtime Support (/ clr: netcore) (NET 6.0).

In this project when the GetControllingUnknown() function is called we have an assert.

IUnknown* _GetRawUnknown() throw()

{ ATLASSERT(_GetEntries()[0].pFunc == _ATL_SIMPLEMAPENTRY); return (IUnknown*)((INT_PTR)this+_GetEntries()->dw); } \

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.
