我正在用VSCode编写一个C++程序。但是，当我按下F5键时，它所做的只是构建项目。我尝试用VSCode创建另一个简单的项目，看看它是否能工作，但没有成功。下面是我的迷你程序

main.cpp

#include <iostream>

int main() {
    int sum = 0;
    for (int i = 0; i < 100; i++) {
        sum += i;
        std::cout<<"Sum: " << sum << std::endl;
    }
    return 0;
}

我试着重新安装VSCode，但没有成功。当我试着调试python脚本时，它工作得很好，所以问题只出在C上。我该如何调试这个调试错误？澄清：我没有从调试器中得到错误。相反，C的调试器根本没有启动。
