what happen with my componentDidUpdate in reactjs?

this is file app.js

...
constructor(props) {
    super(props);
    this.state = {
      todoLists: [],
      inputValue: "",
      currentName: "",
      todoSearch: "",
      idUpdate: "",
      loader: true
    };
  }
 componentDidUpdate(){
    this.setState({
      loader: true
    })
  }
  componentDidMount() {
    axios
      .get("https://5ec912d99ccbaf0016aa8b6f.mockapi.io/todoLists")
      .then((res) => {
        this.setState({
          loader: false,
          todoLists: res.data
        });
      });
  }
...

i added componentDidUpdate in my App but it message : Maximum update depth exceeded. This can happen when a component repeatedly calls setState inside componentWillUpdate or componentDidUpdate. React limits the number of nested updates to prevent infinite loops.
