[Python] Issue: Tests Pass in Run Mode but Fail in Debug Mode with Qt (PySide6 - Python)

I’m encountering a strange issue with my unit tests involving a Qt-based user interface. All my tests work perfectly in Run mode, but as soon as I switch to Debug mode and set a breakpoint anywhere in my code, the tests start failing.

It seems the problem is related to the Qt interface "freezing" when a breakpoint is hit, and it never "unfreezes," preventing the tests from progressing.

Here’s a snippet of the problematic code:

def click_next_from_creation_plg(ctrl: Controller, qt_bot: QtBot, expected_res: bool):
"""
Click on next button from plugin creation panel and check if it's active

aram ctrl: Application controller
aram qt_bot: (QtBot) qt test fixture instance
aram expected_res: expected result on click, true if the button work, false else it doesn't work
:return: None
"""
current_page = ctrl.gui.stackedWidget.currentIndex()
if ctrl.main_window is not None and ctrl.main_window.isVisible():
if expected_res:
QTest.mouseClick(ctrl.create_panel.gui.button_next, Qt.MouseButton.LeftButton)
qt_bot.waitUntil(lambda: ctrl.gui.stackedWidget.currentIndex() != current_page, timeout=WAITING_QTBOT)
assert current_page != ctrl.gui.stackedWidget.currentIndex(), ("The current page should change when "
"the next button is clicked.")
else:
with qt_bot.assertNotEmitted(ctrl.create_panel.nextClicked):
QTest.mouseClick(ctrl.create_panel.gui.button_next, Qt.MouseButton.LeftButton)
assert current_page == ctrl.gui.stackedWidget.currentIndex(), ("The current page should not change "
"when the next button is clicked but "
"is not functional.")

assert ctrl.gui.button_next.isEnabled() is expected_res, ("The next button's enabled state does not match the "
"expected result.")


And this is the error message :

def click_next_from_creation_plg(ctrl: Controller, qt_bot: QtBot, expected_res: bool):
"""
Click on next button from plugin creation panel and check if it's active

aram ctrl: Application controller

current_page = ctrl.gui.stackedWidget.currentIndex()
