Can you give us any more information than that? Literally anything? Version numbers, what application, what it looks like when it crashes, etc.?

My WindowsTerminal version is v1.3.2382.0, remote host is a kali linux, When I type in a very long string like aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa，it would crash. For example, when I execute command echo aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,it would exit the ssh connection.
Error message: **echo aaaaaapacket_write_poll: Connection to xx.xx.xx.xxx port 22: eother [Exited process, code 255] ** .There is no such bug if it is not a preview release,

@Z-LL reported the same issue in #7651 without the preview release. I tried, but I cannot make this happen!

What version of the ssh server are you using on Kali Linux (@PPointCharles) and your remote host (@Z-LL)? Please run ssh -V on the server.

ssh -V

OpenSSH_7.6p1 Ubuntu-4ubuntu0.3, OpenSSL 1.0.2n  7 Dec 2017

It should be noted that this problem of mine occurred after directly entering SSH (in settings.json: "commandline": "ssh user@ip"). Indirect access (such as entering cmd first, then command SSH) does not have this problem

My Kali Linux version: OpenSSH_8.1p1 Debian-1, OpenSSL 1.1.1d 10 Sep 2019
Windows Terminal version: 1.3.2382.0
Windows ssh.exe version: OpenSSH_for_Windows_7.7p1, LibreSSL 2.6.5
PS: As long as it's a copy operation, it crashes, single-line replication also triggers this problem.

@DHowett commented on GitHub (Sep 21, 2020):

Can you try ssh -v -v -v instead of just ssh? It will enable debug logging.

I cannot reproduce this issue, even with my system locale set to zh-CN.

What keyboard layout are both of you using?

I commented "closeOnExit": "always", ans get the following result:

debug3: send - ERROR: Unexpected IO state, io:00000216D927FB10
packet_write_poll: Connection to IP port 22: eother
debug3: Successfully set console output code page from 65001 to 936
debug3: Successfully set console input code page from 65001 to 936

I test it many times, the 00000216D927FB10 is different every time, the others are the same

I also did the same test with CMD.exe and found that the copy operation will still quit,so maybe this is a bug in ssh.exe or the system settings, not windows terminal.

@DHowett commented on GitHub (Sep 25, 2020):

Wow! Thank you for testing that.

Based on that message, it looks like the code in ssh that handles "partial send" (when you give it too much input at one time, it has to send part of it now and part of it later) on Windows is broken.

This would be a good bug to file on the win32-openssh GitHub.

Thank you again.

I find a solution!
The openssh version of windows is 7.x. I uninstalled the openssh that comes with win10 and switched to git ssh. There is no such problem!

The current version of openssh on win10:
OpenSSH_8.3p1, OpenSSL 1.1.1g 21 Apr 2020
