一、连接不上
先定性，如果满足这个现象：
1、vscode使用ssh时，一直提示连接中。并且try1,try2，try3这样循环下去
2、打开终端可见如下循环输出：
[08:48:13.513] Server installation process already in progress - waiting and retrying
[08:48:14.517] Running script with connection command: ssh -T -D 58042 "192.168.31.235" bash

3、你的服务器关闭了外网的连接或者外网很慢
那么，请参考这篇文章：
vscode ssh连接失败_我歌月徘徊、的博客-CSDN博客_vscode连不上ssh
Or

即使解决了问题，也请把vscode的更新关掉，以避免此问题。
二、闪退
多行操作的时候闪退，网上没找到合适的方法。但意外发现，删掉Vscode的缓存之后问题就没有了。
缓存路径:
C:\Users\username\AppData\Roaming\Code\
