Eternal download Breaking saves (Assassin's Creed: Origins)

Hello! I have a problem with the game . Played at 40mph I came to the Fayum where the big lake and then it began , I sail on a boat and have me open the picture and at the bottom it says loading , wait 5 min it was no use . Closed the game Alt F4 , peresypaju save broken :( . Found save your where online time was 10h, began to pass O5 enough 35H, and on the same lake, the same thing happens a couple of days I was in shock did not play. Found backup where nagrano 30 , got to the lake and A5 the same .
I just don't know what to do I hate yubisofta , but I can't leave this game I really like it. MB does anyone have any ideas what it could be ?
