Expo(SDK 51)中expo-router/entry.js无法识别app/_layout.tsx求助

我使用Expo默认模板开发项目已有一周，一直以app目录下的_layout.tsx作为入口组件，代码如下：

import { Stack } from "expo-router";
import { StatusBar } from "expo-status-bar";
import { LogBox } from "react-native";

LogBox.ignoreAllLogs(true);

const RootLayout = () => {
  return (
    <>
      <StatusBar style="light" />
      <Stack>
        <Stack.Screen name="(tabs)" options={{ headerShown: false }} />
      </Stack>
    </>
  );
}

export default RootLayout;

昨日启动Metro Server时，Expo在app目录自动生成了index.tsx文件，启动后显示默认的Hello World界面。修改该index.tsx文件无任何效果，且找不到该界面的组件代码，疑似expo-router/entry.js未识别我的_layout.tsx或新生成的index.tsx。

以下是我的package.json信息：

  },

}

我已尝试的解决方法：

• 执行expo start -c清除缓存
• 在app.json中指定entryPoint：

  {"expo": {
      "entryPoint": "./app/_layout.tsx"
    }
  }
  

• 将_layout.tsx重命名为_app.tsx或index.js
• 参考Expo Router v3无法识别自定义入口文件中_layout.tsx的相关问题但未解决
