A `https://developer.android.com/reference/kotlin/androidx/test/uiautomator/StaleObjectException` exception is thrown when a `https://developer.android.com/reference/kotlin/androidx/test/uiautomator/UiObject2` is used after the underlying `https://developer.android.com/reference/android/view/View.html` has been destroyed. In this case, it is necessary to call `https://developer.android.com/reference/kotlin/androidx/test/uiautomator/UiDevice#findObject(androidx.test.uiautomator.BySelector)` to obtain a new `https://developer.android.com/reference/kotlin/androidx/test/uiautomator/UiObject2` instance.
