Game Kit exception when trying to fetch leaderboards

I'm using Unity 2020.3.33 and an external asset too update and fetch leaderboards, when I replaced the code to use the unity one I see that crashes when fetching leaderboards.

Authentication works fine but this happens when I try to fetch my leaderboards:

Code:

var leaderboards = await GKLeaderboard.LoadLeaderboards(GameCenter.LeaderBoards.Age.ToString());

Stack:
