植物大战僵尸杂交版现已更新到v2.0.88，闪退问题还是偶有发生，参考网上现有的方案，简单实现了一个。

原理就是监控存档目录的文件变化，一旦有新的存档，则将其备份。如发生闪退，则还原备份即可。

原目录：C:/ProgramData/PopCap Games/PlantsVsZombies/pvzHE/yourdata

备份目录：C:/ProgramData/PopCap Games/PlantsVsZombies/pvzHE/yourdata_Backup

#include <iostream>
#include <filesystem>
#include <string>
#include <vector>namespace fs = std::filesystem;void copy_directory(const fs::path &source, const fs::path &destination)
