Python breaks down when running pyqt5 (Process finished with exit code 255). Also, make links clickable to open webpages inside GUI

Python breaks down when I click “Buscar” (“Search” in English) and I cannot find why. I would also like help in making links clickable and opening web pages, like other browsers do.

One of the problems is “Cannot find reference ‘connect’ in ‘function'” and I guess the main problems should lie somewhere there.

The code is below:
