Error when using PyInstaller to create an executable: 'session not created: failed to start Chrome process'

I have an app that needs to open Chrome and automatically send WhatsApp messages. When I run python main.py, everything works as expected. However, when I try to generate a .exe using PyInstaller so that non-Python users can run it, I get the following error: session not created: failed to start Chrome process.

Here is the relevant information:

The chrome.exe and chromedriver versions I am using: both 135.0.7049.84

The code that performs this task:

import pickle
import time
import urllib.parse
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from webdriver_manager.chrome import ChromeDriverManager

def run():
    with open("messages.pkl", "rb") as file:
        messages = pickle.load(file)

    options = webdriver.ChromeOptions()
    options.add_argument("--no-sandbox")
    options.add_argument("--disable-dev-shm-usage")
    options.add_argument(r"--user-data-dir=C:\Users\Urano\AppData\Local\Google\Chrome\User Data")
    options.add_argument("--profile-directory=Default")
    service = Service(ChromeDriverManager().install())
    driver = webdriver.Chrome(service=service, options=options)

    wait = WebDriverWait(driver, 30)

    print("Abriendo WhatsApp Web...")
    driver.get("https://web.whatsapp.com")
    input("Escaneá el código QR y presioná ENTER cuando WhatsApp Web esté cargado...\n")

    for phone, message in messages:
        try:
            print(f"\n📨 Preparando mensaje para {phone}")
            encoded_message = urllib.parse.quote(message)
            url = f"https://web.whatsapp.com/send?phone={phone}&text={encoded_message}"
            driver.get(url)
            print("🔄 Esperando que cargue el campo de texto...")
            message_box = wait.until(
                EC.presence_of_element_located((By.XPATH, '//div[@data-tab="10"]'))
            )
            print("✅ Campo de texto localizado")

            time.sleep(2)

            message_box.send_keys(Keys.ENTER)
            print(f"✅ Mensaje enviado a {phone}")

            time.sleep(3)

        except Exception as e:
            print(f"❌ Error al enviar mensaje a {phone}: {e}")
            continue

    driver.quit()
    print("\n✅ Todos los mensajes procesados.")

if __name__ == "__main__":
    run()

And my project structure (before running any pyinstaller command):

How can I run the pyinstaller to fix this issue?

The problem is that Chrome is not in the same directory or path with all of the users

so I tried to make this code, and it is a small part of yours because you did not provide some additional files like "messages.pkl"

I have deleted this line :

options.add_argument(r"--user-data-dir=C:\Users\Urano\AppData\Local\Google\Chrome\User Data")

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager


def run():
    options = webdriver.ChromeOptions()
    options.add_argument("--no-sandbox")
    options.add_argument("--disable-dev-shm-usage")
    options.add_argument("--profile-directory=Default")
    service = Service(ChromeDriverManager().install())
    driver = webdriver.Chrome(service=service, options=options)

    print("Abriendo WhatsApp Web...")
    driver.get("https://web.whatsapp.com")
    input("Escaneá el código QR y presioná ENTER cuando WhatsApp Web esté cargado...\n")

    driver.quit()
    print("\n✅ Todos los mensajes procesados.")

if __name__ == "__main__":
    run()

then converted it into exe file using this command:

pyinstaller --noconfirm --onefile --console  "your_file.py" --workpath "Final_exe_file/build" --distpath "Final_exe_file/exe"
