运行human_face_recognition/lcd报错 serial.serialutil.SerialException (AIV-602)

前段时间可以烧录例程，今天发现不止这个例程烧录不了，其他例程也烧录不了了，况且烧录过程中会发出USB设备弹出的提示音，然后就报以下错误，请问是什么原因呢？

Traceback (most recent call last): File "D:/ESP32-IDF/esp-tools-offline/Espressif/frameworks/esp-idf-v4.4.4/components/esptool_py/esptool/esptool.py", line 493, in command p = self.read() File "D:/ESP32-IDF/esp-tools-offline/Espressif/frameworks/esp-idf-v4.4.4/components/esptool_py/esptool/esptool.py", line 438, in read return next(self._slip_reader) File "D:/ESP32-IDF/esp-tools-offline/Espressif/frameworks/esp-idf-v4.4.4/components/esptool_py/esptool/esptool.py", line 3661, in slip_reader raise FatalError(msg) main.FatalError: Serial data stream stopped: Possible serial noise or corruption.

During handling of the above exception, another exception occurred:
