ホスト側のOS初期化により同じ現象に遭遇しました。
C:/Users/username/.ssh/known_hosts
に記載されたfingerprintが一致しないことでこの事象が起こっていたようなので、
乱暴ではありますがknown_hostsを削除することで解決しました。
対象IPやホスト名の部分のfingerprintを削除するだけでもうまくいくかもしれませんが、検証できていません。

VSCodeのRemote-SSHで接続出来ない。
Q&AClosed
今回初めてVSCodeでSSH接続を試みています。
VSCodeのRemote-SSHで接続出来ません。
色々やってみたのですが万策尽きました。
どなたかご教授お願い致します。
【開発環境】
エディション Windows 10 Home
バージョン 20H2
OS ビルド 19042.1110
VSCode バージョン: 1.58.1
Remote - SSH v0.65.7
configは最低限の設定にしています。
\Users\user.ssh\config
Host docker
HostName 192.168.1.10

試したこと

・C:\Users\【ユーザ名】.ssh\config ファイルアクセス権を変更
・C:\Users\user.ssh\config を削除して
C:\ProgramData\ssh\ssh_config を作成
・settings.jsonの”remote.SSH.remotePlatform”に、接続相手の名前とOS種別(今回はLinux)を設定。
下記エラー文言から検索
・「プロセスが、存在しないパイプに書き込もうとしました」で検索して1ページ目のサイト。
・「vscode ssh could not establish connection to」で検索して1ページ目のサイト。
等。
宜しくお願い致します。

同じエラーが出て、対象IPやホスト名の部分のfingerprintを削除するだけで解決しました。
記載ありがとうございます。
I encountered the same phenomenon due to OS initialization on the host side.
C:/Users/username/.ssh/known_hosts
This event seems to have occurred because the fingerprints listed in the page do not match, so
Although it was rough, I solved it by deleting known_hosts.
It may work just to delete the fingerprint of the target IP or host name part, but this has not been verified.
