this message appears to me after ubisoft connect tries to allocate disk space. i've got more than 500 gb free of space in my drive though. And it doesn't happen with any other ubisoft game when i try to download it. I'm quite desperate so any help would be appreciated. I want to avoid redownloading the game since it's 116 gb in size

I'm on the mission "seas of fate",where there's a gap between leaving Norway and reaching England where Layla is disconnected from the animus. Each time i try to reconnect to the animus, it loads a bit and then crashes
