Please be aware that the offline installed game phones home to a cloudfront service at 13.224.102.118:443, 13.224.102.15:443, 13.224.102.113:443 and 13.224.102.122:443.

For those disliking home calling apps, block it by your firewall. The game works normal without connection.

What ?

Even if you installed the game via offline installer, and even if you never installed and run Galaxy, the Prey.exe still tries to connect to server-13-224-95-1.zrh50.r.cloudfront.net, which is an Amazon.com, Inc. service. You can see the attempts logged in my firewall (attachment) where it got blocked. You can also use Wireshark or similar to check that. The IP's can looked up like here: https://db-ip.com/all/13.224.95

I hope I interpreted your question right.

Oh I see, but why it is doing that ?

This can have many reasons from error reporting to sending user and system specs, statistical evaluation, location tracking or the unused interface for the multiplayer-dlc. It could also be a third party library that collects data, with or without knowledge of the developers.
Example: In Jun 2018, Zenimax (also publisher of Prey) included "accidentally" the spyware RedShell into the Elder Scrolls Online installer, which than later got removed again after the community complained [1].
One could analyze the packages it tries to send to make an assumption by it's content, or ask the developers. I just block it and inform others.

Thanks for the explanation

Thanks for the heads up. Seems like it's only Prey.exe that's doing this from your screenshot? If so I can just block it but it's a little suspicious this should even occur for a single-player game particularly on GOG tbh.

I asked on the God's Trigger sub-forum here whether their Red Shell spyware was removed and a GOG staffer told me it had been (meanwhile there's no word of its removal on the Steam version, curiously).
