Segmentation fault when attempting to test FApplication

[genedan]

I've got the QApplication subclassed as FApplication:

from PyQt6.QtWidgets import (
    QApplication
)


class FApplication(QApplication):
    def __init__(
        self,
        *argv
    ):
        super().__init__(*argv)

I'm able to run the following test when using a PyCharm context menu or when running the test alone in the terminal. But when I run the entire test suite using $pytest, I wind up with a segmentation fault.

import sys

import pytest

from faslr.core import FApplication

from pytestqt.qtbot import QtBot


@pytest.fixture(scope="session")
def f_application():

    app = FApplication(sys.argv)

    return app


def test_f_application(
        qtbot: QtBot,
        f_application: FApplication
) -> None:

    app = f_application

Some things I've tried doing are adding a line to exit the application. Declaring the application via a fixture was suggested in this guide:
