Bug Summary and Steps to Reproduce

Bug Summary:
After selecting debug configuration, the item "command" in tasks.json is wrong which may cause error of compiling, showing in Debug Console.

Steps to reproduce:

1. Create a new directory.
2. Create a new cpp file. Input the following code into the file.

#include <iostream>
using namespace std;
int main() {
    cout << "Hello, World!";
    return 0;
}

4. Press the play button in the top right corner of the editor. Choose Run C/C++ File. Which is shown in https://code.visualstudio.com/docs/cpp/config-mingw#_run-helloworldcpp
5. Choose C/C++: g++.exe build and debug active file from the list of detected compilers on your system.

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: g++.exe 生成活动文件",
            "command": "D:\\msys64\\ucrt64\\bin\\g++.exe",
            "args": [
                "-fdiagnostics-color=always",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "调试器生成的任务。"
        }
    ],
    "version": "2.0.0"
}

6. Debug Console shows ERROR: Unable to start debugging. Unexpected GDB output from command "-exec-run". During startup program exited with code 0xc0000135.

Expected behavior:
The terminal in the vscode will output "Hello,World!"

And I found the way to solve this problem:
Change "command": "D:\\msys64\\ucrt64\\bin\\g++.exe", to "command": "D:/msys64/ucrt64/bin/g++.exe",
And then everything goes well, and "Hello,World!" can be printed in the terminal.

tasks.json

Start by reproducing the documented MinGW flow and inspect the generated tasks.json command for the Windows path shown in the report. Compare it with the forward-slash workaround; done means the generated task starts debugging successfully and prints Hello, World! in the terminal.
