Program crash caused by disconnect signal

[tom me]

hi，

I'm having trouble writing a program in PyQt5.

When I call child window function in signal slot function. Disconnecting with "disconnect" and then closing the child window crashes the whole program.

But I manually click the button to open the child window. Then use "disconnect" to disconnect the signal connection mentioned above, close the child window and everything works fine.

What is causing this problem?

Looking forward to your reply, thank you.
