xcode升级到11后微信登录返回后app卡死
升级xcode后，旧工程连接真机调试，当手机版本为ios12的时候，微信登录正常，Universal Links正常，回调走的是continueUserActivity
当手机ios版本为13以上时，微信登录返回依然走了continueUserActivity，但是多了一条错误日志
Can't end BackgroundTask: no background task exists with identifier 2 (0x2), or it may have already been ended. Break in UIApplicationEndBackgroundTaskError() to debug.
然后app直接卡死。
以下为全部日志：

ios12一下的手机测试都没问题，唯独ios13不行，Universal Links配置正确，浏览器里都能拉起app。
