Sometimes, the "waiting window" just does not show up.
This seems to happen after "closing" the app, but there's still some process running in the background, and the next time the app is launched, this bug occurs. For now, to avoid this bug, this may need to clear the RAM, or wait for a long time before starting the app again. But I should do a better clean-up when exiting.
