You should set weaponList = new string[3]; inside of start, not globally.

 public string[] weaponList;
  
 void Start(){
     weaponList = new string[3]; 
     weaponList[0] = "Pistol";
     weaponList[1] = "SMG";
     weaponList[2] = "Shotgun";
 }

I tried that but got 2 error s

Only assignment, call, increment, decrement, and new object expressions can be used as a statement

the other one error CS1525: Unexpected symbol `='

That seems to work. Why does it not work if i assign it globally?

Nothing ever happens globally. When a script starts, the global variables are allocated, but they can't be initialized until a function actually runs. Unity runs Start() first, for that exact purpose.

If I solved your problem, please mark the answer as correct.
