here you Component is looking for datosUsuario variable inside that component that's why your getting that error to fix this

Component

  <template>
    <div class="tabla-usuarios">
        <table class="table table-hover table-striped">
            <thead>
                <th>ID</th>
                <th>NOMBRE</th>
                <th>EMAIL</th>
                <th>DIRECCIÓN</th>
                <th>CONTRASEÑA</th>
            </thead>
            <tbody>
                <tr v-for="usuario in datosUsuario" :key="usuario.id">
                    <td>{{ usuario.id }}</td>
                    <td>{{ usuario.nombre }}</td>
                    <td>{{ usuario.email }}</td>
                    <td>{{ usuario.direccion }}</td>
                    <td>{{ usuario.password }}</td>
                </tr>
            </tbody>
        </table>
    </div>
</template>

<script>
export default {
    data() {
        return {
            datosUsuario: [],
        };
    },
    created: function () {
        this.cargar();
    },
    methods: {
        cargar: function () {
            let url = "/getDatosPersonales";
            axios
                .get(url)
                .then((response) => {
                    this.datosUsuario = response.data;
                })
                .catch((error) => console.error(error));
        },
        enviar() {
            let url = "/actualizarDatos";
            axios
                .post(url, {
                    id: this.id,
                    nombreUsuario: this.nombreUsuario,
                    email: this.email,
                    password: this.password,
                    direccion: this.direccion,
                })
                .then(function (response) {
                    this.arrayTasks = response.data;
                })
                .catch(function (error) {
                    console.log(error);
                });
        },
    },
};
</script>

and remove function form app.js
