关键摘要:

• 在launchProcessByAM函数中，使用qCWarning而不是qWarning来记录日志，以便更好地区分错误和警告信息。
• launchProcessByAM函数中的错误处理逻辑没有处理reply.errorName()，这可能会导致在错误处理时出现空指针异常。
• launchProcessByAM函数中的return语句应该在qCWarning之后立即执行，而不是在QTimer::singleShot之后。
• DBusServer::showDeepinSystemMoniter函数中的launchProcessByAM调用应该放在QTimer::singleShot的回调函数中，而不是直接在函数中调用。
• DBusServer::showDeepinSystemMoniter函数中的launchProcessByAM调用应该使用launchProcessByAM函数本身作为回调函数，而不是使用[]()匿名函数。
