Adb suddenly disconnected. After reconnecting, the page structure can no longer be obtained

Version:appium-uiautomator2-server-v4.27.0

When searching for a control in a Pop Window, adb suddenly disconnected. After reconnecting, the page structure can no longer be obtained, but the page on the device is fully displayed.(Why?)
Is there any solution?thanks
