Question

所以我正在尝试使用PyQt5和Qt设计器构建MySQL数据库编辑器并且我已经定义了一个按钮以运行用于连接的自定义方法，但是每次按此按钮都不会发生连接时，应用会关闭，然后我得到“处理结束，退出代码为-1073740791（0xC0000409）”

我尝试过的事情：

使用mysql.connector代替sqlalchemy
回滚我的图形卡驱动程序（我的笔记本电脑有两个图形卡，我不知道PyCharm使用哪个图形卡，但我回滚了主要的图形卡）

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