[Bug]传输断连之后不会返回主界面

[nkdns]

在断开连接之后，会卡在下载数据的页面，不会返回主界面
该星球是行星工厂，数据量大但是代理服务器带宽小，从而经常发生下载到一半断开连接的问题。

After disconnecting, it will get stuck on the download data page and will not return to the main interface
This planet is a planetary factory with a large amount of data, but the bandwidth of the proxy server is small, resulting in frequent disconnection issues when downloading halfway.
