How to disable [UnixSelectorEventLoop] warning

[re1oaded]

Loop <_UnixSelectorEventLoop running=False closed=True debug=False> that handles pid 1919221 is closed
Loop <_UnixSelectorEventLoop running=False closed=True debug=False> that handles pid 1919232 is closed
Loop <_UnixSelectorEventLoop running=False closed=True debug=False> that handles pid 1923783 is closed
Loop <_UnixSelectorEventLoop running=False closed=True debug=False> that handles pid 1923796 is closed
Loop <_UnixSelectorEventLoop running=False closed=True debug=False> that handles pid 1924099 is closed

A large number of continuous warnings.
UnixSelectorEventLoop always appears on my console and affects the running log of the program I want to print.

I tried many methods and couldn't disable it.

Do you have a reproducible script for it?

import threading
import schedule
from playwright.sync_api import sync_playwright

play_counts = 0

def play():
    global play_counts
    with sync_playwright() as p:
        browser = p.chromium.launch()
        context = browser.new_context()
        context.route("**/*", lambda route: route.abort() if route.request.resource_type == "image"  else route.continue_())
        
        page = context.new_page()
        page.goto("https://outlook.live.com/owa/")
        page.wait_for_selector(".sign-in-link")
        
        play_counts += 1
        print("\r" + "play_counts: " + play_counts, end="")

        browser.close()


def auto():
    while True:
        try:
            play()
        except Exception:
            continue


def daily_counts():
    global play_counts
    play_counts = 0
    print()


def daily_counts_task():
    schedule.every().day.do(daily_counts)
    while True:
        schedule.run_pending()


def run(threadIndex):
    for _ in range(threadIndex):
        threading.Thread(target=auto).start()
    threading.Thread(target=daily_counts_task).start()
        
run(5)

Run it until it reappears.

I am experiencing the same but only on sync api, and was able to resolve it and fyi it is indeed a bug in playwright's process handling in the sync api.
