CTkMessagebox Popup instantly closed after opened

[1lunea]

So I was replacing tk message box with CTkMessagebox but when I ran the code and tested it, the messagebox instantly closed

        password = self.teachers_password_signup.get()
        confirm = self.teachers_confirm_password_signup.get()
        username = self.teachers_username_signup.get()
        name = self.teachers_name_signup.get()
        if (name or username or confirm or name) == "":
            CTkMessagebox(title="Error", message="Please fill out the form!", icon="OK")
        elif password == confirm:
            with open("data/teachers.txt", "a") as file:
                data = f"{username}:{password}:{name}"
                file.write(data)
                file.write("\n")
            CTkMessagebox(title="Sign Up Successful",message=f"Sign Up successful! Please return to the login site.",icon="check", option_1="OK")
        else:
            CTkMessagebox(title="Error", message="Passwords don't match", icon="OK")
