Frequent get-stuck incidents at the same location during gameplay

This is the "Leisurely" level in Jinan Yaoqiang. There were no issues before, but after closing the game midway through one playthrough, it has been stuck at the same point (05:55:25) ever since, with the game not responding. I don’t know what’s going on, and reinstalling the game didn’t fix it. The same issue hasn’t occurred in any other levels so far.I had edited this level before, but that was before I reinstalled the game; I haven’t edited it since the reinstallation.

P.S.: I hope you’ll add an option to exit the game mid-play and return to the main menu.
