Visual Studio Code – VSCode Debugger not Launching

I am writing a C++ program in VSCode. However, when I press F5, all it does is build the project. I tried making another simple project in VSCode to see if it works, but no luck. Here is my mini-program

launch.json

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
      {
        "name": "C/C++: clang++ build and debug active file",
        "type": "cppdbg",
        "request": "launch",
        "program": "${fileDirname}/${fileBasenameNoExtension}",
        "args": [],
        "stopAtEntry": true,
        "cwd": "${workspaceFolder}",
        "environment": [],
        "externalConsole": false,
        "MIMode": "lldb",
        "preLaunchTask": "C/C++: clang++ build active file"
      }
    ]
  }

tasks.json

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: clang++ build active file",
            "command": "/usr/bin/clang++",
            "args": [
                "-fcolor-diagnostics",
                "-fansi-escape-codes",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "Task generated by Debugger."
        }
    ],
    "version": "2.0.0"
}

main.cpp

#include <iostream>

int main() {
    int sum = 0;
    for (int i = 0; i < 100; i++) {
        sum += i;
        std::cout<<"Sum: " << sum << std::endl;
    }
    return 0;
}

I have tried reinstalling VSCode with no luck. When I try to debug a python script, it works just fine, so the problem is only with C++. How do I debug this debugging error?
CLARIFICATION: I am not getting an error from the debugger. Instead, the debugger for C++ isn’t launching at all.

    Instead, the debugger for C++ isn’t launching at all.

    Because you are missing the debugger’s path in your launch.json. Add a path to the debugger within the miDebuggerPath.

    {
  "version": "0.2.0",
  "configurations": [
    {
      "name": "C/C++: clang++ build and debug active file",
      .
      .
      "miDebuggerPath": "/path/to/gdb"
    }
  ]
}

    Or, you can use the Add Configuration button (visible in launch.json) to set up a new debugging configuration.

    You can do following steps and see if it works:

    • do not forget to save file with ‘ctrl + s’ before running it.
    • include path of c++ "bin" folder to your environment variables, vs code automatically detects c++ debugger.
    • install code runner extension on vs code.

    do share your results..
