[🐛 Bug]: Segmentation fault when trying to stop a driver in qt

[iyamk]

What happened?

I made a program but it causes constant segmentation faults when I stop it with the stop button! Help

How can we reproduce the issue?

Solved by switching to PySimpleGUI! The problem is gone. QT is a flat thing
