Please could you enclose your code in triple backticks (`) characters so that the indentation is retained.

added main.txt plz verify it

I can't replicate this. I ran your code on an ESP32-S3. I had to change one of the pin numbers and also added a print statement:

from mqtt_as import MQTTClient, config
import asyncio
from machine import Pin

# Local configuration
config['ssid'] = 'misspiggy'
config['wifi_pw'] = 'my password'
config['server'] = '192.168.0.10'  # Change to suit e.g. 'iot.eclipse.org'

pin23 = Pin(13, Pin.OUT)  # Blue LED (pin 23 is invalid on my board)
pin23.off()
pin18 = Pin(18, Pin.OUT)
pin18.off()

async def messages(client):  # Respond to incoming messages
    async for topic, msg, retained in client.queue:
        t = topic.decode()
        m = msg.decode()
        print(t, m)  # Added print statement

        if t == "esp32/relay1":
            if m == "on":
                pin23.on()
            elif m == "off":
                pin23.off()

        if t == "esp32/relay2":
            if m == "on":
                pin18.on()
            elif m == "off":
                pin18.off()

async def up(client):  # Respond to connectivity being (re)established
    while True:
        await client.up.wait()  # Wait on an Event
        client.up.clear()
        await client.subscribe('esp32/relay1', 1)  # renew subscriptions
        await client.subscribe('esp32/relay2', 1)

async def main(client):
    await client.connect()
    for coroutine in (up, messages):
        asyncio.create_task(coroutine(client))
    n = 0
    while True:
        await asyncio.sleep(5)

config["queue_len"] = 1  # Use event interface with default queue size
MQTTClient.DEBUG = True  # Optional: print diagnostic messages
client = MQTTClient(config)
try:
    asyncio.run(main(client))
finally:
    client.close()  # Prevent LmacRxBlk:1 errors

The messages were received correctly and the blue LED behaved as expected. I tested as follows (typical message):

$ mosquitto_pub -h 192.168.0.10 -t esp32/relay1 -m "on" -q 1

As far as I can tell mqtt_as is behaving correctly.

sorry my mistake i was not paying attension to wiring, i connected them to series thats why LEDs behave like that,
