VS code debugger doesn't open terminal - c++

Question

I'm trying to create a cpp environment on vs code. The build works, .exe gets generated, but the debugger doesn't seem to work. When I click on the run debug option, another terminal gets open with a message (attached in the screenshot). The code which I'm running is a simple hello world example. No terminal with Hello World is opened by the debugger. Hello world is supposed to be displayed in the screenshot of terminal 2 but another message gets printed, which I got no clue about.
Terminal 1
Terminal 2
This is the code for the config files:
task.json

{
"label": "build",
"type": "shell",
"command": "g++",
"args": [
"sample.cpp"
],

}
]
}
launch.json
{
