What are the reasons setState does not change the state?

Question

React

This function, for unknown reasons, does not change the state. Tried to use other state functions, also used regular class functions. But the state of the application still does not change.
What could be causing this?

import React from "react";
import '../CSS/CaseContainers.css';

export default class Winners extends React.Component{
    constructor(props) {
        super(props);

        this.state = {
            answer: [],
            login: null
        };
    }   
    async componentDidMount(){
        await fetch(this.props.conf + "connect/winlist", {
            method: "get"
        }).then(response => {return response.json()})
        .then(response => console.log(response))
        .then(response => this.setState({answer: response}));
    }
    render(){
        console.log("outFetch");
        console.log(this.state.answer);
        return(
            <div className="Winners">
              <h3>{}</h3>
            </div>
        );
    }
}

Take away: The call to console.log returns undefined, which is passed on to setState.
.then(response => console.log(response))
