How do I handle pyqt no response?

I made a program using pyqt and selenium. While executing the code, there was no response, so I specified the thread, but I don't think I can get the cache value from another class.

Here's the error message:

TypeError: 'cached_property' object is not callable

I searched a lot. I can't find the answers I want, so I'm posting questions. I'm sorry.
