Pyqt5 QtWebEngineWidgets | Problem with opening the site on the site

Question

Pyqt5 QtWebEngineWidgets | Problem.

There is a website (https://sites.google.com/view/aerlis-page-sites/).

If you open the site, then everything is OK. But if you try to open the site by clicking on the button open site on the site. She won't work anymore. No matter how hard I try. Button does not work. How can I fix this problem?

There is another problem if you open Spotify, for example, there will be an error at the entrance. I don't know why but the site refuses to work. Can you help me solve this problem too?
