Vanish - Failed to compile: There is no argument given that corresponds to the required parameter 'index' of 'BasePlayer.ResetAntiHack(int, NativeArray<AntiHack.PlayerSpeedhackState>, NativeArray<AntiHack.PlayerFlyhackState>)' | Line: 448, Pos: 41

Error while compiling Vanish: The type or namespace name 'EntityNetworkRange' could not be found (are you missing a using directive or an assembly reference?) | Line: 1142, Pos: 55

I have fixed this issue, saw the code as Vanish.cs and upload it. Set to go :)
