PsychoStats 3.2.8b安装中止问题求助

我在正常可用的XAMPP服务器上安装PsychoStats 3.2.8b时失败，服务器环境配置：Apache/2.4.46 (Win64) OpenSSL/1.1.1g PHP/7.4.16。

报错信息如下：

Installation Aborted! The installation was halted due to your session either timing out or another installation session was started! You must start over and try again. Be sure not to open a second installation window or it will fail again.

我注意到安装脚本似乎未设置继续安装所需的Cookie，相关逻辑位于common.php文件中，关键的会话初始化代码已高亮标注：
