For me “This video is currently unavailable. Please try again. Error code: 3005”
does not prevent the download from being with the current SF version
edit: more info in post 13 here
But the video can be downloaded normally.
And in the new Paramount+ Downloader, we don‘t need to play back the video
If you still need a solution, use SF <7012
If you have a problem name at least title and country.
Ideally attach your StreamFab.log
