Try/except on all app

[mattthhh]

Hi there! I wanted to know if there is a solution to catch all exceptions from the whole app running, I tried this code following :

if __name__ == "__main__":
    try:
        app = App()
        ret = app.run()
    except Exception as err:
        print("sad")

but it didn't work... I got the exception with rich printing but it's not handled by my try/except in my main. Any ideas ?
