上传Sketch到ESP32 Camera Wrover时持续报错：Invalid head of packet (0x00)

上传Sketch到ESP32 Camera Wrover时反复触发Invalid head of packet (0x00)错误，已完成以下排查操作但均无效：

更换多个USB端口测试
重置ESP32 Camera Wrover、IO扩展板及UNO板
将上传波特率从默认921600 baud逐步降至115200 baud及最低档位
上传过程中按住重置按钮
确认电脑已安装对应驱动，无缺失

按Elegoo智能机器人套件V4.0官方组装说明完成接线，IO扩展板已切换至上传模式，排除接线问题。另外已通过板载WiFi在本地服务器成功查看实时画面，确认摄像头硬件无故障。

上传失败的终端输出

Serial port /dev/cu.usbmodem00001
Connecting......................................

A fatal error occurred: Failed to connect to ESP32: Invalid head of packet (0x00): Possible serial noise or corruption.
Failed uploading: uploading error: exit status 2

#include <stdlib.h>
#include "WiFiInfo.h"

const char* ssid = "wifi";
const char* password = "passsword";

// int setenv(const char* password, const char* password);

    Serial.begin(9600);
  delay(1000);

  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);
