ESP-IDF问题：vTaskDelay()调用后STA管理任务停止运行

我正在构建一个运行APSTA模式的ESP系统，用户可通过向URL提交JSON字符串，控制ESP连接/断开其他AP（如路由器）。操作完成后，布尔值_STA_START会被设为true，登录参数存入_STA_WIFI_SSID和_STA_WIFI_PASS。

编写STA连接管理任务时遇到问题：调用vTaskDelay()后，vTask_Manage_STA_Connection()代码停止运行；删除该语句后，代码会快速循环导致栈溢出并复位ESP。目前监控显示该任务仅运行一次。start_Manage_STA_Connection()是在初始化ESP为AP后于main.c中调用的。
