[🐛 Bug]: webdriver.Edge() fails on some machines with "Unsuccessful command executed", despite same environment

[SherlockTN]

Description

What happened?

When running the following code:

from selenium import webdriver
driver = webdriver.Edge()

The browser starts correctly on some machines, but on others, the following error occurs:

selenium.common.exceptions.WebDriverException: Message: Unsuccessful command executed:

Additional information

• All machines have the latest versions of Microsoft Edge and Selenium.
• The issue happens regardless of proxy settings.
• Changing Python and Selenium versions does not resolve the problem.
• Even using a different PC results in the same error for affected users.
• Manually specifying the path to a downloaded msedgedriver.exe makes the browser start successfully.

Steps to reproduce

The cause is unclear because the environment is reportedly identical.

Environment

• OS: Windows 10 / 11
• Browser: Microsoft Edge (latest version)
• Selenium version: 4.x (tested with several versions)
• Python version: 3.x (tested with several versions)

Expected behavior

Edge browser should launch without specifying the driver path manually.

Actual behavior

WebDriverException is thrown unless the driver path is specified explicitly.

Note

I have not yet confirmed if the exact same error occurs on all affected machines.
The provided error log is from a representative case where the issue was reproducible.

Reproducible Code

from selenium import webdriver

# 何も指定せずEdgeを起動しようとするだけの最小コード
driver = webdriver.Edge()

# 動作確認のために簡単なページを開く
driver.get("https://www.google.com")
