Python 3.10.9导入_ctypes时DLL加载失败求助

Windows 10 Pro系统中，原Python 3.9.13-amd64运行正常。卸载该版本并删除C:\Users\Admin\AppData\Local\Programs\Python\Python310\目录后，安装Python 3.10.9-amd64，运行脚本时出现如下错误：

已尝试以下解决方案：

• 使用pip卸载并重新安装pandas；
• 通过注册表将C:\Users\Admin\AppData\Local\Programs\Python\Python310\DLLs\添加到系统路径；
• 将libcrypto-1_1.dll、libssl-1_1.dll、libffi-7.dll从上述DLLs目录复制到脚本所在目录。

以上方案均未解决问题，寻求技术协助。
