Steps to Reproduce:
a simple rust program to produce the bug

use std::env;
use std::process::Command;

fn main() {
    let args: Vec<String> = env::args().collect();

    if args.len() < 2 {
        println!("Usage: {} <file_path> [additional args...]", args[0]);
        return;
    }

    let vsc_exe = "D:\\Program Files\\Microsoft VS Code\\Code.exe";

    let output = Command::new(vsc_exe).args(&args[1..]).output();

    match output {
        Ok(_) => println!("Successfully launched VS Code with provided args"),
        Err(e) => println!("Launch failed: {}", e),
    }
}

launcher.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "vsc_process",
            "type": "cppvsdbg",
            "request": "launch",
            "program": "${workspaceFolder}/target/debug/vsc_process.exe",
            "args": ["${workspaceFolder}/.vscode/launch.json"],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
            "environment": [],
            "console": "integratedTerminal"
        }        
    ]
}

boot from debug and vscode will not do anything, boot from cmd is ok.

golang as the same

package main

import (
    "fmt"
    "os"
    "os/exec"
)

func main() {
    args := os.Args

    if len(args) < 2 {
        fmt.Printf("Usage: %s <file_path> [additional args...]\n", args[0])
        return
    }

    vscExe := "D:\\Program Files\\Microsoft VS Code\\Code.exe"

    cmd := exec.Command(vscExe, args[1:]...)
    err := cmd.Run()

    if err != nil {
        fmt.Printf("Launch failed: %v\n", err)
    } else {
        fmt.Println("Successfully launched VS Code with provided args")
    }
}

launcher.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch Package",
            "type": "go",
            "request": "launch",
            "mode": "auto",
            "program": "${workspaceFolder}/main.go",
            "args": ["${workspaceFolder}/.vscode/launch.json"],
        }
    ]
}

This is used in unreal jump to source:

According to original issue: https://github.com/microsoft/vscode/issues/264119#issuecomment-3246398555

I've tried ELECTRON_RUN_AS_NODE and still not working. Setting ELECTRON_RUN_AS_NODE to 0 or 1 even blocks vscode from booting.

I think this is a bug not a settings problem.
