Ubisoft Connect Can't Start Download (Assassin's Creed: Valhalla)

Unable to load ASV. Already 3-4 times I delete and try to download it, at the same place the download gets up and that's it, the speed appears for a couple of seconds and drops again. And so a vicious circle. He writes that there are supposedly problems with the Internet connection or there is not enough memory on the disk, but in fact the Internet is working and there is enough disk space for the eyes. I tried to run Ubisoft as an administrator and reinstalled the service itself, changed the download speed, changed proxy settings and other ways to solve problems that I found on the Internet, but this is not enough, because nothing helps. Technical support is silent, they do not want to return the money for the game, the matter is at an impasse. If someone solved such a problem, let me know in what way.
