VScode's debugger not working [MacOS - Clang - C] - c

Question

My problem is generated when trying to debug C (the programming language) in vscode using the latest MacOS version with command line tools installed.
The error appears when the external terminal is launched in order to debug. I'm using the clang compiler with the following configuration files for the debugger in vscode:
launch.json:
{

"type": "cppdbg",

"cwd": "${fileDirname}",
"environment": [],
"externalConsole": true,

"preLaunchTask": "C/C++: clang build active file"
}
]
}
tasks.json:

},
{

"label": "C/C++: clang build active file",
"command": "/usr/bin/clang",
"args": [
"-g",

"-o",

"group": {
"kind": "build",

},

}
],
"version": "2.0.0"
}
The error that appears in the terminal:
