debug clang (lldb) under vscode/windows - debugging

Question

I'm trying to debug the helloworld project
#include <stdio.h>
int
main (void)
{
printf ("Hello, world!\n");
return 0;
}
which is built using clang. I use vs-code to take these actions. Here is my task.json file:
{
"version": "2.0.0",
"tasks": [
{
"type": "shell",
"label": "C/C++: clang.exe build active file",
"command": "C:\\msys64\\mingw64\\bin\\clang.exe",
"args": [
"-g",
"${file}",
"-o",
"${fileDirname}\\${fileBasenameNoExtension}.exe"
],
"options": {
"cwd": "${workspaceFolder}"
},
"problemMatcher": [
"$gcc"
],
"group": "build"
}
]
}
As a build task, it works but then with launch.json to debug it seems with no progress. Here is my launch.json` file:
{
// Use IntelliSense to learn about possible attributes.

{

"type": "cppdbg",
"request": "launch",
"program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
"args": [],
"stopAtEntry": true,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": false,
"MIMode": "lldb",
"miDebuggerPath": "C:\\msys64\\mingw64\\bin\\lldb.exe",
"setupCommands": [
{

"text": "-enable-pretty-printing",
"ignoreFailures": true
}
],
"preLaunchTask": "C/C++: clang.exe build active file"
}
]
}
How to set-up debugger under vs-code with the use of clang/lldb?
It got stall within this command
