My Python code works perfectly when I debug it in Visual Studio Code, but it closes as soon as I hit enter when I open it in the command prompt

First of all I literally just now made an account here so I apologize if I’m posting this wrong or something. But anyway:

Basically what the title says. I’m making a text-based fake OS (weird I know, but bear with me) using Python. When I tested it in Visual Studio Code’s debugger, everything worked perfectly. However, I wanted to test it in the same environment that my future users will, so I right-clicked the file in File Explorer and selected open with Python, which of course brought me to the command prompt.

All was going well until I hit enter, then text appeared on the screen for like a nanosecond and the command prompt window just closed.

I looked it up and many people are saying to add a text input, but mine has several already and it’s still closing. And again, please note that it works fine in Visual Studio Code’s debugger.

I don’t think I should post all 400 lines of code, but I’ll put the important parts of the code below:

import time
import getpass

#Start of Bootup:

def welcome_user():
    print("Welcome to rOS!")

def boot_up():
    time.sleep(1)
    print("Booting up...")
    time.sleep(3)
    print("The system has successfully booted.")

#End of Bootup
    
#Start of Login:

def get_password():
    password = getpass.getpass("Enter your password: ")
    return password

def create_password():
    password = getpass.getpass("Create a password: ")
    return password

def save_password(password):
    with open("password.txt", "w") as file:
        file.write(password)

def load_password():
    try:
        with open("password.txt", "r") as file:
            password = file.read().strip()
            return password
    except FileNotFoundError:
        return None
    
#End of Login

def calculator():
    #My calculator code doesn't have anything to do with the problem so I'm not posting it now.
    pass

def antivirus():
    #Again, it's not necessary for this post; it's here as a placeholder.
    pass

def desktop():
    print("------------------------------")
    print("DESKTOP")
    while True:
        program = input("Enter a program name: ")
        #The programs are simulated fyi
        if program == "list":
            print("------------------------------")
            print("Antivirus")
            print("Calculator")
            print("------------------------------")
        elif program == "antivirus":
            antivirus()
        elif program == "calculator":
            calculator()
        else:
            print("Invalid program name. Please try again.")
            continue

#More of the login stuff:

def login():
    password = load_password()
    if password:
        while True:
            entered_password = get_password()
            if entered_password == password:
                print("Login successful!")
                desktop()
                break
            else:
                print("Incorrect password. Please try again.")
    else:
        password = create_password()
        save_password(password)
        print("Password created!")

def main():
    welcome_user()
    boot_up()
    time.sleep(1)
    login()

if __name__ == "__main__":
    main()

Hope that code isn’t too long. My real code is much much longer.

But anyway, whenever I open the py file and hit "enter" after I’ve created a password in the program, text appears but it immediately exits out of command prompt. But it’s fine in VS Code.
