VSCode中C++调试突发Launch: program does not exist错误求助

我使用VSCode编写C++已有两个月，此前一切正常。上周开始突发「Launch: program does not exist」等调试错误（目前已出现两次），同一程序在不同文件中运行会显示不同错误。该程序用于USACO铜级竞赛，上传至在线评测平台可正常运行，但在VSCode中仅特定程序出现此问题。

已尝试以下方案均无效：

• 重命名文件
• 复制程序到新文件
• 修改launch.json
• 卸载重装VSCode

仅文件中写入简单Hello World可正常运行，功能相同的其他代码也无法运行，今日另一无关程序也出现相同错误。

附当前launch.json配置：
