The Crew or The Crew 2? Like coley said, the servers are offline for The Crew (1) and it's been removed form uplay entirely (which I was not aware of). The reason why it's an issue with The Crew AND it will be a problem for both The Crew 2 (not yet offline) and The Crew Motorfest is those games have a constant internet connection requirement to play the singleplayer campaign. So once the servers go down, unless you have a workaround to host a dummy server or get the offline mode working, the game is just dead sadly enough. Forza Horizon 4 does not have any such requirement so it'll be fine.
