Windows10下pip安装/搜索报错ProtocolError: PermissionError(13)求助

• 系统环境：Windows 10
• Python版本：3.12.4（从python.org下载），对应pip版本24.0
• 问题现象：执行pip install 'package name'或pip search 'package name'命令始终报错；此前pip功能正常，使用Chocolatey后出现该问题
• 网络验证：同一网络下的笔记本可正常执行pip install命令

执行pip install pyautogui时的错误输出：

$ pip install pyautogui

执行网上找到的类似curl pypi(...).org | (...)命令时，出现与firefox.browser文件相关的错误。

已尝试以下方法，但均未解决问题：

• 关闭防火墙
• 以管理员身份运行命令
• 使用--user参数
• 创建并使用虚拟环境（venv）
• 卸载并重新安装Python/pip
• 将Python添加到系统环境变量Path中
• 检查并调整256字符路径长度限制设置
• 执行pip install --upgrade pip，仍报相同错误
• 单独执行curl https://pypi.org/simple/pyautogui/命令可正常返回内容
