Script works in editor but not XAML build

I have a project that includes a coin system that is saved to a path. Every time the game is loaded, the coins will try to load into a TMPro object. Here is the script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using TMPro;
5. using System;
6. using System.IO;
7. using System.Reflection;
8.  
9. public class ScriptManager : MonoBehaviour
10. {
11.     public TextMeshProUGUI tmp;
12.     string coins;
13.     int cc;
14.  
15.     // Start is called before the first frame update
16.     void Start()
17.     {
18.         if (File.Exists(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\gameccint.gamec"))
19.         {
20.             coins = File.ReadAllText(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\gameccint.gamec");
21.             tmp.text = coins.ToString();
22.             UnityEngine.Debug.Log("Loaded coins: " + Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments));
23.         }
24.         else
25.         {
26.             cc = 0;
27.             File.WriteAllText(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\gameccint.gamec", cc.ToString());
28.             coins = File.ReadAllText(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\gameccint.gamec");
29.             tmp.text = coins.ToString();
30.             UnityEngine.Debug.Log("Loaded coins: " + Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments));
31.         }
32.     }
33. }

But when I build the project in Debug mode, it gives me these errors in the development console:

Code (CSharp):

1. DirectoryNotFoundException: Could not find a part of the path "C:\Users\Admin\Documents\gameccint.gamec"
2.  
3. DirectoryNotFoundException: Could not find a part of the path "C:\Users\Admin\Documents\gamecgint.gamec"
4.  
5. FormatException: Input string was not in a correct format

I can't seem to figure out why it works perfectly fine in the editor but not in the build.

 

Should you probably be using Application.persistantDataPath to be reading/writing files in the context of Unity?

 

So all I need to do is to replace:

Code (CSharp):

1. Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)

with this?

Code (CSharp):

1. Application.persistentDataPath
