Opening more than one brave profile using selenium python

[Mor1]

I'm trying to open multiple brave profiles at the same time using the following code:

from selenium import webdriver 
import time 
from selenium.webdriver.chrome.service import Service
drivers = [] 
for i in range(1, 5):
     option = webdriver.ChromeOptions()
     option.binary_location = "path to brave.exe" 
     option.add_argument(f"--profile-directory=Profile {i}")
     option.add_argument(f"--user-data-dir=AppData\\Local\\BraveSoftware\\Brave-Browser\\User Data")
     s = Service(chromedriver)
     driver = webdriver.Chrome(service=s, options=option) driver.get("https://google.com")        drivers.append(driver) time.sleep(6)

but upon executing, it opens 2 brave instances and then terminates. 
it also gives me the following error:

[Sir Jo]

you can try to use different port on each instances using

option.add_argument(f"--remote-debugging-port=xxxx")
xxxx maybe, for example, 9222+i

It still gives the same error.

Pls check you are setting new devtools port for each seesion and validate port is free before assinging it

I checked for the availability of the ports before assigning every profile a port and it still gives the same error.

Maybe try to set diff debug port for each instance
