CreateBitmapFromMemory executes successfully when _nWidth is equal to or less than 644. If the value exceeds this value, the HRESULT value is -2003292276
Do limits exist on the width and height?

Are you sure you passed in the correct pixelFormat for function CreateBitmapFromMemory? you hard code it to GUID_WICPixelFormat24bppRGB, I think this is the root cause, you should make sure this format same as the format with the source bitmap which you are copy the data from. try use the GetPixelFormat function to get the correct format instead of hard code.
