D3D11 CreateDeferredContext Error without ever creating a deferred render context

Question

I get the following error message in my output window :-

D3D11 ERROR: ID3D11Device::CreateDeferredContext: Creation of a Device with D3D11_CREATE_DEVICE_SINGLETHREADED prevents the creation of deferred contexts. [ STATE_CREATION ERROR #2097162: CREATEDEFERREDCONTEXT_SINGLETHREADED]

D3D11 ERROR: ID3D11Device::CreateDeferredContext: CreateDeferredContext returning DXGI_ERROR_INVALID_CALL, meaning the function can not be used. [ STATE_CREATION ERROR #2097164: CREATEDEFERREDCONTEXT_INVALID_CALL_RETURN]

But I never call that function and also I have a single threaded immediate render context. This started happening abruptly.

Also, If i do a search for that function call then i get 0 hits in my entire solution.

Update 1 - The culprit seems to swap hain present because even if I don't create any shaders and buffers and just the context device and swapchain I still get this error

Update 2 - I have already tried the following -

1. Re-build the solution in debug and release mode.
2. Attaching the debugger by directly running the program on different graphic cards.
3. Re-installing DirectX.
4. Upgrading/Downgrading graphics and audio drivers.
5. going back to an old system restore point.
6. Re-installing Visual Studio
