捕获元素执行时报错

An unknown server-side error occurred while processing the command. Original error: io.appium.uiautomator2.common.exceptions.UiAutomator2Exception: Timed out after 15521ms waiting for the root AccessibilityNodeInfo in the active window. Make sure the active window is not constantly hogging the main UI thread (e.g. the application is being idle long enough), so the accessibility manager could do its work
