StudioX Powerpoint Automation Interop Com component Issue

Hello forum members,
I am trying automation with PowerPoint using StudioX

Uipath StudioX
2020.10.2
Community Edition

Something went wrong with an Action.
Activity Delete Slide (Delete Slide) failed:
Unable to cast COM object of type ‘System.__ComObject’ to interface type ‘Microsoft.Office.Interop.PowerPoint._Presentation’. This operation failed because the QueryInterface call on the COM component for the interface with IID ‘{9149349D-5A91-11CF-8700-00AA0060263B}’ failed due to the following error: The RPC server is unavailable. (Exception from HRESULT: 0x800706BA).
