RLS moved to Desktop and its not letting me setup in Desktop

Hi 

 I did some RLS last week in Fabric semantic model in service , now I went to do the same for another model , I see message that its moved to desktop so I downloaded the report and opened model tab , Roles grayed out , then I tried new report in desktop connecting to dataset still same result , now how to  I build roles in semantic model 

Service: 

Desktop for same model 

How do I setup roles now ?  My PBI version is : Version: 2.132.1053.0 64-bit (August 2024)

Thanks
