I had write a simple test demo, the qt original method work fine, but qasync not working?

Code Sample

fromqasyncimportQEventLoopasEventLoop, asyncSlotimportasynciofromqtpy.QtCoreimport*fromqtpy.QtWidgetsimport*asyncdefmain(app:QApplication, win:QWidget):
ev=asyncio.Event()
app.aboutToQuit.connect(ev.set)
win.show()
awaitev.wait()
app=QApplication()
win=QPushButton("test")
@asyncSlot()asyncdefon_click(*args):
print("xx1")
win.clicked.connect(on_click)
defon_click1():
print("good")
win.clicked.connect(on_click1)
asyncio.run(main(app, win), loop_factory=EventLoop)
