appium-xcuitest-driver v9.10.5 / appium-server v2.19.0 - When using element.click() it results in appium server/WDA crashing on iOS 26 Simulator

[zacht-saucelabs]

This python test code produces the exception:

Python libs used:

• Appium-Python-Client==5.2.4
• selenium~=4.27.0

next_button = WebDriverWait(driver, 10).until(EC.presence_of_element_located((AppiumBy.ACCESSIBILITY_ID, "next_button")))
next_button.click()

Caps:

  "alwaysMatch": {
    "platformName": "iOS",
    "appium:deviceName": "iPhone Air",
    "appium:platformVersion": "26.1",

    "appium:newCommandTimeout": 3600,
    "appium:app": "/Users/zach/Src/appium-examples/app_downloads/HN-arm.zip"
  },

The same error happens if I use driver.find_element().

is el.click() deprecated? I ask this because if I use the ActionChains API it works just fine, and I can replace my el.click calls with:

def click(driver, element):
    ActionChains(driver).move_to_element(element).pause(5).perform()

Could you share the device log as well? It might be a condition-specific issue. We haven't seen crash issue in appium/appium#21347 for element client endpoint call.

Also, please try out with the latest xcuitest/WDA as well
