The method stops working when i call Add() but there are ZERO exeptions. this is in the piece class.

protected bool CopyInfoToGlobals(){
        List<(int x, int y)> ew = range.Keys.ToList();
        print($"dasf  {ew.Count - 1}"); //prints numbers usally above 2
        for(int r = 0; r < ew.Count - 1; r++){ 
            print($"yfdhg {ew[r].x}, {ew[r].y}" );// prints once correctly
            globals.PieceInteractions[ew[r].x, ew[r].y].Add(range[ew[r]]);//where i think the problem is
        }
        print("yuo");//never prints
        return true
    }

the second print() should call several times but only once. the last one never prints . this is for chess in unity2d.

when i did this nothing happens:

if(CopyInfoToGlobals()) print("sucsess at last"); else print(32);//it prints nothing

PieceInteractions decloration in globals which i dont think matters:

public static List<Piece.LocalBoardRepresention>[,] PieceInteractions = new List<Piece.LocalBoardRepresention>[8,8];

what range is:

public Dictionary<(int x, int y),LocalBoardRepresention> range = new Dictionary<(int x, int y), LocalBoardRepresention>(); 

idk if this matters either

public class LocalBoardRepresention 
    {
        public Piece @this{internal set; get;}
        public bool r{internal set; get;};
        public bool l{internal set; get;};
        public Piece p{internal set; get;};
    }
