I'm trying to make a stock program with pyqt5, but when I click the add button, I get the python stopped error

from PyQt5.QtWidgets import*
from stock_python import Ui_MainWindow
import sqlite3



class mysia_stock(QMainWindow):

    def __init__(self):
        super().__init__()

        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
        self.ui.pushButton_tablo_ekle.clicked.connect(self.kayit_ekle)



    def kayit_ekle(self):

        komponentadi = self.ui.lineEdit_adi.text()
        komponentdegeri = self.ui.lineEdit_degeri.text()
        komponentturu = self.ui.lineEdit_turu.text()
        stokmiktari = int(self.ui.lineEdit_stok_miktari.text())
        urunkategori = self.ui.comboBox_urun_kategori.currentText()
        try:
            baglanti = sqlite3.connect("urunler.db")
            islem = baglanti.cursor()
            baglanti.commit()

            ekle = "INSERT INTO urun VALUES(?,?,?,?,?)"
            islem.execute(ekle, (komponentadi, komponentdegeri, komponentturu, stokmiktari, urunkategori))
            baglanti.commit()
            self.ui.statusbar.showMessage("Kayıt Başarılı", 2000)


        except ValueError:
            self.ui.statusbar.showMessage("Kayıt Başarısız", 2000)
        except sqlite3.OperationalError:
            self.ui.statusbar.showMessage("sqlite", 2000)




uygulama = QApplication([])
pencere = mysia_stock()
pencere.show()
uygulama.exec_()

You do not do proper error checking, such as for opening the database or executing the query --- do so. Step through your code in a debugger, or put in print() statements to see where it gets to.
