PyQt5 'Process finished with exit code -1073740791 (0xC0000409)'

so I'm trying to build a MySQL database editor using PyQt5 and Qt designer and I've defined a button to run a custom method for connection but every time I press the button connection won't happen, app closes and then I get 'Process finished with exit code -1073740791 (0xC0000409)'

Things I've tried:

• using mysql.connector instead of sqlalchemy
• rolling back my graphic card driver (my laptop has two graphic card i don't know which one does the PyCharm uses but i rolled back the main one)

from PyQt5 import QtCore, QtGui, QtWidgets
from mysql.connector import connect
