为什么这个run_no_ui的脚本在之前的版本可以运行，升级到4.4.0后就运行不了了呢？请教大神该怎么修改？

SETTINGS["log.file"] = True

event_engine = EventEngine()
main_engine = MainEngine(event_engine)
main_engine.add_gateway(TtsGateway)
cta_engine = main_engine.add_app(CtaStrategyApp)
main_engine.write_log("主引擎创建成功")

log_engine = main_engine.get_engine("log")
event_engine.register(EVENT_CTA_LOG, log_engine.process_log_event)
main_engine.write_log("注册日志事件监听")

main_engine.connect(ctp_setting, "TTS")
main_engine.write_log("连接CTP接口")

sleep(10)

cta_engine.init_engine()
main_engine.write_log("CTA策略初始化完成")
sleep(30)

cta_engine.init_all_strategies()
sleep(60)   # Leave enough time to complete strategy initialization
main_engine.write_log("CTA策略全部初始化")

cta_engine.start_all_strategies()
main_engine.write_log("CTA策略全部启动")
