Game Kit service activated = NullReferenceException when I build (2021.2)

[BenoitFreslon]

Hello,

I downloaded the 2021.2 iOS Native pro and I installed the asset on an empty Unity project 2021.3 and 2020.3
I got the same problem when I active the Game Kit service and when I build the project.

NullReferenceException: Object reference not set to an instance of an object

Error:

if (capability.GameCenter.Enabled) capManager.AddGameCenter();

Do you have the same problem?
