Because it’s not cracked, it has denuvo, the only way to get passed it is by getting a token by someone who owns the game that is unique to you and is only valid for 20 mins, once you raise a ticket on the discord a caretaker will issue you your ticket, it’s the only way around denuvo at present. You also won’t have to sign out of your own steam account and can launch the game directly without the steam launcher, although steam must be installed on your machine.
