VS code, remote ssh unable to connect

Question

I tried to follow the instructions from "VS Code Remote Development" to ssh into some Linux (RHEL 7 & 8) servers. Keep getting the same error: - Failed to connect to the remote extension host server (Error: spawn Unknown system error -8). The log seems to suggest failure occurs when Checking ssh with "ssh -V". However, I have no issue running ssh -V in the terminal:

> ssh -V
OpenSSH_9.0p1, OpenSSL 1.1.1f  31 Mar 2020

> type ssh
ssh is hashed (/bin/ssh)

My local machine is running MacOS 13.2.1 (Ventura)
My several colleagues have no issue using the Remote SSH extension to connect to the same Linux servers. I am the only one hitting this issue.
In my Mac terminal, I have no issue ssh into the same Linux servers.
I assume it has something to do with my own setup, I’ve exhausted all of the troubleshooting tips and tricks on https://code.visualstudio.com/docs/remote/troubleshooting website. Nothing helps.
It appears that the VS code remote extension has not even reached the point to install the vscode server on the Linux server, as the .vscode-server directory has not been created, before the failure took place.
