jest test is not exiting after test passes with react-test-renderer

I have a toMatchSnapshot test on a simple component with React Native 0.68.2/jest 29.0. Here is the component SysError:

import React, {useState, useContext, Component} from 'react';
import {Platform, Button, Text, TouchableOpacity } from 'react-native';

export default function SysError({route}) {
    const message = route.params.message;
    return (
        <Text>{message}. System NOT available right now. Try again later</Text>
    )
};

Here is the SysError.test.js:

import React from 'react';
import renderer from 'react-test-renderer';  //<<==v17.0.2
import SysError from './SysError';

it ('describe SysError page view with no message', () => {
    const route = {params: {message:"noth"}};
    const tree = renderer.create(<SysError route={route} />).toJSON();
    expect(tree).toMatchSnapshot();
})

After yarn test --detectOpenHandle, test passes but is not exiting by itself. Here is the error for component SysError:

  Jest has detected the following 2 open handles potentially keeping Jest from exiting:

  ●  MESSAGEPORT

There is no async call in SysError.js and what is missing here?
