我的任务是按文件名查找文件。搜索必须从C：\驱动器启动。当我在其他驱动器上测试我的功能时，比如D：\或A：\，一切都很好，但我试图用C：\驱动器来做，我使用的是g编译器，C 17，Windows操作系统。调用main.cpp中的函数

try {
        if (SearchFile::find_file(fs::path("C:\\"), fileName)) {
            return 0;
        }
    } catch (const fs::filesystem_error& e) {
        std::cerr << "Error accessing filesystem: " << e.what() << std::endl;
        std::cerr << "Exception path1: " << e.path1() << std::endl;
        std::cerr << "Exception path2: " << e.path2() << std::endl;
    }
    for(const auto& drive : drives){
        fs::path drivePath(drive);
        std::string driveLetter = drivePath.string().substr(0, 1);
        if (!(driveLetter == "C" || driveLetter == "c")) {
            if (SearchFile::find_file(drivePath, fileName)) {
                break;
            }
        }
    }

我的函数，位于SearchFile类中

大多数时候我都是这样的：“文件系统异常：文件系统错误：无法递增递归目录迭代器：尝试运行程序时参数“”无效。我也尝试AdjustPriviledges，但它仍然没有解决问题。此外，我还试图以管理员身份运行它，并禁用Windows Defender，仍然没有结果。
