json - python：无法从线程中的文件加载json数据

Question

所以，我正在开发一个 Steam 帐户生成器（现在是 GUI），但我遇到了一个问题。我有一个获取生成帐户的线程，URL并且在某些时候，它调用一个函数来更改包含有关帐户信息URL的文件中的值。JSON当它尝试调用它时，我得到一个JSONDecodeError，但是当我运行该函数来单独更改值时，它可以完美运行。

该线程正在主GUI文件中运行，它正在调用另一个 py 文件，其中包含一些函数（steam_api_gandler_rewrite文件），该changeJSONAccountValue函数调用另一个 py 文件中的函数。

[线程（在主文件中）-> steam_api_handler_rewrite -> json_func]

---

加载文件和更改值的功能

import json


def changeJSONAccountValue(value, player, dict):
    with open('files/accounts.json') as fp:
        data = json.load(fp) ##<---- Loading JSON File
    for acc in data['accounts']:
        if acc['name'] == player:
            acc[dict] = value
            with open('files/accounts.json', 'w') as json_file:
                json.dump(data, json_file, indent=2)

JSON：
