Answer 1

Another hour of Google, and I still managed to find the answer, in order for the font to work we need: Download this font * .ttf and drop it into the folder with the program files, this is necessary in order to specify the exact path to font, regardless of the computer on which your application is installed, additional actions from the user are also not required. And so what we do:

app = QtWidgets.QApplication(sys.argv)
    myapp = Interface()
    myapp.show()
    sys.exit(app.exec_())

In this part of the code, where we have to render the window, we need to add our font to the base, the code will look like this:

app = QtWidgets.QApplication(sys.argv)
    QtGui.QFontDatabase.addApplicationFont(fr'путь к нашему шрифту')
    myapp = Interface()
    myapp.show()
    sys.exit(app.exec_())
