System.IO sharing error despite closing the read and write

system.io is giving a sharing file error when using these two functions (not simultaneously) here are the two functions that handle saving and loading from what i can tell it looks to be something to do with loading because it can load fine but when trying to save after a load it will give a sharing error but i haven't tested it the other way around, i know the code is long but i wanted to include both functions because the error code (from what i can see) doesn't tell much info about what line caused the error but rather the error within System.IO itself there are a few lines in the error that are associated with the saving function though but i think its referring to what it was calling rather than the saving function leaving its stream Writer open and not closing it

 function saveGameList ()
 {
     var sw : StreamWriter = new System.IO.StreamWriter(Application.dataPath + "/" + "games.list");  //opened to same directory
     for(var i = 0; i < names.length; i++)
     {
         sw.WriteLine(fitToFileFormat(i)); //loops through slots and combines info in 7 different arrays to 1 variable to look like "hello-1-1-1-1-1-1"
     }
     sw.WriteLine("#"); //signals the array info is over
     sw.WriteLine(core.money); //writes player variables
     sw.WriteLine(core.compName); //writes player variables
     sw.WriteLine(core.playerName); //writes player variables
     sw.Close();    //both read and write are being closed
 }
 
 function loadGameList ()
 {
     var sr : StreamReader = new System.IO.StreamReader(Application.dataPath + "/" + "games.list"); //opened to same directory
     var found = false;
     for(var i = 0; i < 15 && found == false; i++)
     {
         var line = sr.ReadLine();
         Debug.Log(line); 
         if(line == "#") //checks to see if the array info is over then sets the player variables after the for loop
         {
             found = true;
         }
         else
         {    
             var game = line.Split("-"[0]);
             addNewGame(game[0],parseInt(game[1]),parseInt(game[2]),parseInt(game[3]),parseInt(game[4]),parseInt(game[5]),parseInt(game[6])); //adds the info to the 7 arrays described at the top
         }
     }
     core.money = parseInt(sr.ReadLine()); //sets player variables
     core.compName = sr.ReadLine(); //sets player variables
     core.playerName = sr.ReadLine(); //sets player variables
     sr.Close(); //both read and write are being closed
 }

here is the full error that unity gives

ive tried alot of techniques to help with it like .flush() and .Dispose() but its still gives the sharing error
