On October 1st 2022, Ubisoft shut down the DLC authentication servers for Assassins Creed 3. If you played the game before this date, the authentication was grandfathered into your cloud save. However if you didn't, the DLC will not activate and will forever remain unplayable.

Another really annoying aspect of the servers being shut down is the game takes a really long time to start up as it's still programmed to wait for the servers to work.

There is however a hacked version of Uplay's .dll files that bypass this check. Allowing you to play its dlc without the need to authenticate.

The fix is located here:

After downloading the zip extract all of the files into your game folder.

NOTE: This fix does remove syncing with cloud saves. So you'll most likely need to start a new game.

That's about it. Note this fix will not remove needing to log into Uplay/Ubisoft Connect on startup. It just removes the game authenticating with its dlc servers. I hope this works for you.
