.exe file is working with sqlite but when convert into window executable file it can't save data in database

from tkinter import *
import tkinter as tk
import tkinter.messagebox as tkMessageBox  
import sqlite3

#function to define database
def Database():
    global conn,cursor
    #create person database
    conn=sqlite3.connect("regform.db")
    cursor=conn.cursor()
    #creating person_reg table
    cursor.execute('''
                CREATE TABLE IF NOT EXISTS PERSON(
     pr_id INT AUTO_INCREMENT PRIMARY KEY,
     pr_name VARCHAR(50),
     pr_age VARCHAR(10),
     pr_gender VARCHAR(50),
     pr_email VARCHAR(50),
     pr_phone VARCHAR(50)
     
     )

 ''')

    Database()
    #getting form data
    name1=e1.get()
    age1=e2.get()
    gender1=e3.get()
