I'm having the same issue

Would you like to provide a minimal working example to reproduce the problem?

[GOUYONGCHAO]

in background.py

 def start(self, *args, **kwargs):
        if self._event is None or self._event.is_set():
            self._event = Event()

        BaseScheduler.start(self, *args, **kwargs)
        self._thread = Thread(target=self._main_loop, name='APScheduler')
        self._thread.daemon = self._daemon
        self._thread.start()

add:

self._thread.join()

i dont know why
but it works
I'm ussing python python 3.10.6
apscheduler 3.5.0
