Can confirm this is the case on Debian 9 as well with the latest version. Hopefully a relatively quick patch will be released like the previous one.

I'm investigating right now, I'll be working on it and will try to patch it over the next hours.

same problem for me. I had to reinstall 3.9.3

Same issue here

This was because the version field was not set on v0.2.2 of cloud-agent.
I've released v0.2.3 to address this - this will be in a 3.10.1 patch release that will be out in the coming days, but until then, a quick fix would be to replace /usr/lib/code-server/lib/coder-cloud-agent with the latest release from https://github.com/cdr/cloud-agent/releases/latest/download/cloud-agent-$OS-$ARCH. ($OS is darwin for macOS / linux for linux, and $ARCH is amd64/arm64)

For example:
sudo curl -fsSL "https://github.com/cdr/cloud-agent/releases/latest/download/cloud-agent-linux-amd64" -o /usr/lib/code-server/lib/coder-cloud-agent

@naseefalikp6273 it looks like you're on macOS so that won't work. If you installed code-server with homebrew then you need to run:
sudo curl -fsSL "https://github.com/cdr/cloud-agent/releases/latest/download/cloud-agent-darwin-amd64" -o /usr/local/Cellar/code-server/3.10.0/libexec/lib/coder-cloud-agent and type in your password.

For others, here's how you can figure out where code-server lives and how to fix it:

1. where code-server this tells you where the bin folder is. on macOS, you get /usr/local/bin/code-server
2. if you cat that file, you get something like this:

#!/bin/bash
PATH="/usr/local/opt/node@14/bin:$PATH" exec "/usr/local/Cellar/code-server/3.10.0/libexec/out/node/entry.js"  "$@"

Looking at the exec path, we see where code-server's files actually live.
3. Now if we cd into /usr/local/Cellar/code-server/3.10.0/libexec, we'll see a lib folder.
4. We can type cd lib and type ls and we'll see the coder-cloud-agent. Now we have the output path which we can use with that curl command suggested by @oxy
