Qt applications always need a QApplication instance to be created first, and to then exec it to start the event loop. When you are inside the Maya UI there is already an instance of QApplication running so you don't have to do it yourself. So that bring said, have you tested this code from the Maya Script Editor? In this terminal output, you can also see that it is warning you that it is picking up your system PySide2, causing it to load two versions of Qt5. This is also a potential for crashing once you get beyond the problem of not having created a QApplication in the terminal. You have to make sure you pick up Maya's PySide2 first. -- > You received this message because you are subscribed to the Google Groups > "Python Programming for Autodesk Maya" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To view this discussion on the web visit > https://groups.google.com/d/msgid/python_inside_maya/CACsi_51r%3DYSzYM2WxfujE_vD4MHNGbLgKNNZ9050AqjT28%2BHuA%40mail.gmail.com > <https://groups.google.com/d/msgid/python_inside_maya/CACsi_51r%3DYSzYM2WxfujE_vD4MHNGbLgKNNZ9050AqjT28%2BHuA%40mail.gmail.com?utm_medium=email&utm_source=footer> > . > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "Python Programming for Autodesk Maya" group.
