React native, setState is undefined

I'm re-learning React native as the back isn't dev yet I'm starting fake data, so in my Modal I'm trying to put in my state future api data

import React,{useEffect,useState} from "react";
import { Modal, StyleSheet,Text,TouchableOpacity, ScrollView,View,Image } from "react-native";

const ModalInfo = (props) => {
    const {toggleVisibility,visibility} = props
    const [genre,setGenre] = useState(null);


    useEffect(() => {
        setGenre({
            id:"genreID",
            name:"Les Tops",
            description:"Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec at ullamcorper eros.",
            icons:[{url:"https://t.scdn.co/media/derived/toplists_11160599e6a04ac5d6f2757f5511778f_0_0_275_275.jpg"}],
        })
    },[]);

    return (
        <Modal animationType="slide" transparent={true} visible={visibility}>
            <View style={styles.modalView}>
                <View style={styles.modalHeader}>
                    {
                        genre && genre.icons ? <Image source={{uri: `${genre.icons[0].url}`}} style={styles.images} /> : null
                    }
                    {
                        genre && genre.name ? <Text style={styles.modalText}>{genre.name}</Text> : null
                    }
                </View>
                <ScrollView style={styles.modalScroll}>
                    {
                        genre && genre.description ? <Text style={styles.modalText}>{genre.description}</Text> : null
                    }
                </ScrollView>
                <View style={styles.modalFooter}>
                    <TouchableOpacity onPress={()=>{toggleVisibility()}} style={styles.btn}>
                        <Text style={styles.btnTxt}>Rejoindre</Text>
                    </TouchableOpacity>
                </View>
            </View>
        </Modal>
    );
};

export default ModalInfo;

But somehow genre is still undefined and if I don't pu ternary I've an error saying undefined.

UPDATE: when I passed something else than an Object to setGenre It work's
