After disconnecting and reconnecting adb, the page structure cannot be obtained

[WuXiaoJun111]

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?)

The Logcat logs are as follows：
