Error freezes UI and does not print traceback to terminal

Consider the following code:

import sys
from PySide2 import QtWidgets

def on_pressed():
    priknt("world")  # misspelled


app = QtWidgets.QApplication(sys.argv)
button = QtWidgets.QPushButton("Hello")
button.pressed.connect(on_pressed)
button.show()
app.exec_()

When I hit the button, there's an error since the function "priknt" doesn't exist.

• With PySide2, the UI will freeze up and not generate a traceback in the terminal
• With PyQt5, the UI will crash instantly and generate a traceback in the terminal
• With PySide and PyQt4, the UI will keep being functional and generate a traceback in the terminal

Would it be possible to achieve the same functionality as seen in PySide/PyQt4 where the UI doesn't freeze or crash instantly?

My motivation behind this is I really prefer "nothing happens when I click the button!" instead of "aaaw f@¢$, I lost all my work!".
