You may check whether the game’s service is available with HITMAN Status, a useful website made by fellow member @Hardware. As of right now, services for every platform look to be online, so I’d suggest you tp check your PC/console’s Internet connectivity, otherwise checking whether the platform online service is available.

I’ve also had the same issue, for about as long. I’ve reset my wireless network, tried different settings, etc. What’s strange is yesterday morning, I was able to actually launch the game and played for around 9 hours, with some prompting to reconnect to the network. After I closed the game and came back to it after a couple hours, I got the same “fetch” error again. Still having the same problem now.
Have any of you checked your Xbox store, I got the deluxe version but it’s saying I need to buy it again, might be something to do with it going on game pass as “free”. I’m also getting the failed to fetch error, I’ve reported it but wondered if any of you have the same thing with the store?
