Additional Information

LLDB is in the PATH which is reasonable to use in this situation:

% which lldb
/usr/bin/lldb

The vscode-cpptools extension uses gdb with mi mode, or lldb-mi for its deubgging purposes, not lldb.

Interesting, why it shows the message "Unable to find GDB in default search path and Applications/Xcode.app/Contents/Developer/Toolchains/X
codeDefault.xctoolchain/usr/bin/lldb"?

I'm also getting this issue on a brand new M2 Mac Mini.
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin no longer has any sort of lldb.

[proc] Executing command: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lldb --version
[proc] The command: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lldb --version exited with code: 127

What gets me farther is to edit my settings.json to point directly to the pre-packaged one:

{
	"cmake.debugConfig": {
		"miDebuggerPath": "/Users/{Your User Name}/.vscode/extensions/ms-vscode.cpptools-1.14.3-darwin-arm64/debugAdapters/lldb-mi/bin/lldb-mi"
	}
}

I also had to chmod it as well:

chmod +x /Users/{Your User Name}/.vscode/extensions/ms-vscode.cpptools-1.14.3-darwin-arm64/debugAdapters/lldb-mi/bin/lldb-mi

Though now my debugging experience is very unstable. Seeming to hang at the first breakpoint and unable to evaluate local variables of any kind.

Specifying the miDebuggerpath to an lldb-mi extension worked for me:

    {
            "name": "Test",
            "type": "cppdbg",
            "program": "${workspaceFolder}/build/src/myprogram",
            "request": "launch",
            "cwd": "${workspaceRoot}",
            "MIMode": "lldb",
            "miDebuggerPath": "/Users/rogerhu/.vscode/extensions/ms-vscode.cpptools-1.17.5-darwin-arm64/debugAdapters/lldb-mi/bin/lldb-mi",
            "args": ["--arg1"]
            ]
        }
