[The+Real+Taff]

Morning - I have been watching Sky Go on my Mac with out issue for years but now when I try to open it I get a message saying "Downloading Updates" then that disappears and I get this quit message. I have been reporting it to Apple but it keeps doing it.

My Mac is MacOS High Sierra - appreciate any help - thanks
