Message: Unable to cast COM object of type ‘System.__ComObject’ to interface type ‘Microsoft.Office.Interop.Excel._Workbook’. This operation failed because the QueryInterface call on the COM component for the interface with IID ‘{000208DA-0000-0000-C000-000000000046}’ failed due to the following error: The application called an interface that was marshalled for a different thread. (Exception from HRESULT: 0x8001010E (RPC_E_WRONG_THREAD)).

How about implementing dispatcher. it will release unmanaged resources used by your application.
Or something like this using dispose for the reference.

PS: Does both studio has same excel packages version?. Can you update if available and try.
How about using workbook activity not within excel scope.

does your excel macro have Close Application activity? if yes remove it.
