无法在reducer中的未安装组件上执行React状态更新

Question

我越来越无法在本机应用程序中的未安装组件错误上执行React状态更新，我已经通过了几种无法解决问题的可用解决方案 请帮助我了解我在这里做错了什么，

这是我在reducer中尝试过的

const Home = (dispatch) => {
  let isUnmount = false;
  return async () => {
    try {
      const response = await Server.get("/user/home");
      if (!isUnmount) {
        if (response.data.flag == true) {
          dispatch({ type: "StoreData", payload: response.data.data });
        } else {
          dispatch({
            type: "addError",
            payLoad: "Something went wrong please try again",
          });
        }
      }
    } catch (error) {
      dispatch({
        type: "addError",
        payLoad: "Something went wrong please try again",
      });
    }finally{
       isUnmount = true;
    }
  };
};

和组件useEffect

useEffect(() => {
    let isUnmount = false;
    if (!isUnmount) {
      Home();
    }
    const listner = navigation.addListener("didFocus", () => {
      if (!isUnmount) {
        Home();
      }
    });
    return () => {      
      listner.remove();
      isUnmount = true;
    };
  }, []);
