Appium server stops during creating session by Appium-Python-Client

Here is my python file

import unittest
import argparse

from pathlib import Path
from appium.options.common import AppiumOptions
from appium import webdriver


class MyTestCase(unittest.TestCase):
    def get_appium_server_url(self):
        def is_docker():
            cgroup = Path('/proc/self/cgroup')
            return Path('/.dockerenv').is_file() or cgroup.is_file() and 'docker' in cgroup.read_text()

        # return f'http://host.docker.internal:4723' if is_docker() else f'http://127.0.0.1:4723'
        return f'http://127.0.0.1:4723'

    def test_session_create(self):

        appium_server_url = self.get_appium_server_url()
        caps = {
            "platformName": "Android",
            "newCommandTimeout": 300,
            "appium:options": {
                "appPackage":  "android app package name",

                "clearDeviceLogsOnStart": True,
                "autoGrantPermissions": True,
            }
        }

        appium_options = AppiumOptions()
        appium_options.load_capabilities(caps)

        driver = webdriver.Remote(appium_server_url, options=appium_options)
        self.assertIsNone(driver)

if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument(
        "--device-udid",
        required=True,
        help="Device udid or IP of a target device")
    args, unknown = parser.parse_known_args()
    print(f"Device UDID: {args.device_udid}")

    if not unknown:
        unknown = ['']

    unittest.main(argv=[unknown[0]] + unknown[1:])

I tried to execute this file with the STF connected device.

Segmentation fault (core dumped)

I checked appium liveness by curl command with endpoint '/status', so just ignore about /status logs. By the way, why this appium server should be communicated with 'http://127.0.0.1:4723' instead of 'http://host.docker.internal:4723'?

Start with session.py and the Appium server log, especially the POST /session request and the final adb start-server command. Reproduce the session against the STF device, compare 127.0.0.1 with host.docker.internal from the container, and inspect the adb crash. Done means identifying a reproducible cause and a confirmed correction or documented environment limitation.
