Python'ValueError:I/O closed file上的操作，同时在循环中获取输入（我没有打开任何文件）

Question

在我们开始之前，这个问题只发生在linux设备上，当我在Windows上尝试它时，它工作得非常好，下面是一些规范

OS: Ubuntu 20.04
Python Version: Python 3.9.2

无论如何，问题是，当我在循环中第二次尝试获取输入时，它会给我一个“ValueError:I/O operation on closed file”，即使我不使用任何文件。以下是错误：

下面是创建此错误的代码

        while (True):
            if (len(self._user_requesting) == 0):
                continue

            for index, user in self._user_requesting.items():

                user = UserSettingsSchema().load(user)
                accept = ''

                # Errors out here on the second while(True) loop iteration
                answer = inquirer.text(
                    message= f'The user "{user.username}" is requesting to join, accept request?',
                    validate= lambda text: text.lower() in ['y', 'yes', 'n', 'no'],
                    invalid_message= 'Please answer with a yes or no (y/n)'
                ).execute()

                if (accept.lower() in ['yes', 'y']):
                    self._user_requesting = []
                    self._opponent = user

                    sock.send_str('accepted', user.private_topic)
                    break

                else:
                    sock.send_str('declined', user.private_topic)

                    self._user_requesting[user.private_topic] = None

                    print(f'The user "{user.username}" is declined ...')
                    print('Waiting for a user to connect ...')

                    continue
            else:
                self._user_requesting = dict(filter(lambda x: x[1] != None, self._user_requesting.items()))

我使用的是InquirePy，但这与错误没有任何关系，因为当我使用本机input()函数时，它仍然会给我相同的错误

我真的不知道发生了什么，因为我不使用任何文件来运行它，我的代码也不涉及任何打开或关闭文件

谢谢你抽出时间
