[haosenwang1018]

What

Replace 9 bare except: clauses with except Exception:.

Why

Bare except: catches BaseException, including KeyboardInterrupt and SystemExit, which can prevent clean process shutdown and mask critical errors. Using except Exception: catches all application-level errors while allowing system-level exceptions to propagate correctly.
