Sky Go v24.1.3-3 now seems to be working on my Intel / Ventura mac.
I did have to manually move the newly downloaded app from '/Users/.../Applications' to the proper location in the '/Applications' folder. Without doing this, the installer was stuck in a loop - automatically reopening the old app version, firing up the separate installer app, downloading the update, quitting itself and then reopening the old app version only to repeat the whole thing over and over and over ad infinitum.
Quitting the installer and moving the newly downloaded Sky Go app myself seems to have stopped this endless loop and the app now apparently runs, as it last did in late May.
