编译运行通过，但是弹出无法打开：267272320315313343267250.cpp，找不到文件

Question

VSCode
源代码是一个很简答的cpp文件，只涉及标准库导入。
编译和运行都通过了，只是有这样一个错误警告,如下图。
267272320315313343267250.cpp不是我的文件，那么这个是如何来的？为什么要打开这个文件？编译运行仍然通过了？
问题很菜鸟，不知道去查找哪方面的问题，跪谢

红框放大如下：

launch.json如下：

// https://github.com/Microsoft/vscode-cpptools/blob/master/launch.md
{
    "version": "0.2.0",
    "configurations": [
        
        {
            "name": "(gdb) Launch", // 配置名称，将会在启动配置的下拉菜单中显示
            "type": "cppdbg", // 配置类型，这里只能为cppdbg
            "request": "launch", // 请求配置类型，可以为launch（启动）或attach（附加）
            "program": "${fileDirname}/${fileBasenameNoExtension}.exe", // 将要进行调试的程序的路径
            "args": [], // 程序调试时传递给程序的命令行参数，一般设为空即可
            "stopAtEntry": false, // 设为true时程序将暂停在程序入口处，我一般设置为true
            "cwd": "${workspaceFolder}", // 调试程序时的工作目录
            "environment": [], // （环境变量？）
            "externalConsole": true, // 调试时是否显示控制台窗口，一般设置为true显示控制台
            "internalConsoleOptions": "neverOpen", // 如果不设为neverOpen，调试时会跳到“调试控制台”选项卡，你应该不需要对gdb手动输命令吧？
            "MIMode": "gdb", // 指定连接的调试器，可以为gdb或lldb。但目前lldb在windows下没有预编译好的版本。
            "miDebuggerPath": "gdb.exe", // 调试器路径。
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": false
                }
            ],
            "preLaunchTask": "Compile" // 调试会话开始前执行的任务，一般为编译程序。与tasks.json的label相对应
        }
    ]
}

task.json文件如下：

                "${file}",
                "-o", 
                "${fileDirname}/${fileBasenameNoExtension}.exe",
                "-g",
                "-Wall",
                "-static-libgcc",
                "-std=c++11"
            ],
            "type": "shell",
            "group": {
                "kind": "build",

                "panel": "shared"
            },
            "problemMatcher":"$gcc"
        }
    ]
}
