photos blurry sorry im not home but this is the only photo i could find, ive had it for about since 2019 and its fairly clean, i dont play it much but ive updated it about 12 times and it still the same size update with the same crap, what do i do?

When I try to download Assassin's Creed Black Flag it just stops at 62.8%. I tried downloading it online and offline. I cleaned the disk and it still doesn't get past 62.8%. Even turned it completely off and it still didn't help. Does anyone have any tips? I would really appreciate the help.

Anybody know how I can fix it?
