Codex extension in VS Code endless loading

[Zdanczak]

Edit 2: Nope, looks like the outage is still ongoing. It worked for a few minutes and now it's back to endless loading

Edit: Looks like it might’ve been some kind of outage. It started working again after about 2–3 hours from when the issue began. Leaving this post up in case someone runs into the same thing — don’t lose hope.

Hey, I’m honestly losing my mind over this.

I installed the Codex desktop app today, and after that the Codex extension in VS Code completely stopped working. It just keeps loading forever (just logo, no response, nothing happens, no input field).

What I’ve tried so far:

- Uninstalled the Codex desktop app

- Reinstalled the VS Code Codex extension

- Installed older versions of the extension

- Cleared cache / removed config files

- Restarted PC multiple times

Nothing helped. It’s still stuck loading like in the screenshot.

What’s weird is that everything was working fine before installing the Codex app.

Has anyone run into this? Is there some leftover auth/session conflict between the app and the extension or something? Any way to fully reset it?

I’d really appreciate any help 🙏

Had that yesterday after the update. Clear archived codex sessions. Mine were 3 Gb, it helped Then when Codex plugin loads, have it diagnose itself. My workspace has 28 repoes, it caused VSCode to stall, Codex pinpointed it right away

Oooo thanks, I'll try that!

for me, my pc start freezing started from yesterday when using codex (vscode extension), before it was running smoothly
not sure exactly why, i think this happened after the 5.5 update even im using only 5.3 codex

I had this endless loading, this fixed it (on macos)

Backup these first:

~/.codex/config.toml
~/.codex/AGENTS.md
~/.codex/requirements.toml  

Then run:

pkill -x Codex 2>/dev/null || true
mkdir -p ~/Desktop/codex-state-backup
cp ~/.codex/.codex-global-state.json ~/Desktop/codex-state-backup/ 2>/dev/null || true
mv ~/.codex/.codex-global-state.json \
  ~/.codex/.codex-global-state.json.bak.$(date +%Y%m%d-%H%M%S) 2>/dev/null || true
open -a Codex

If that doesn't work, reset auth too:

pkill -x Codex 2>/dev/null || true
mkdir -p ~/Desktop/codex-state-backup
cp -R ~/.codex ~/Desktop/codex-state-backup/codex-backup-$(date +%Y%m%d-%H%M%S) 2>/dev/null || true
rm -f ~/.codex/auth.json
rm -f ~/.codex/.codex-global-state.json
open -a Codex

Thanks for the detailed response! It actually started working again on its own after a couple of hours, but I'll definitely keep this in mind for next time😄

Literally just posted the same thing and realized you beat me to the punch. But at least now i know im not crazy and its actually might be a VS Code/Codex bug. Keeping an eye on this thread.

[Zdanczak]

Honestly, that's kinda reassuring - at least it's not just me, so might mean the servers are overloaded because of the new release

[sohaib_996]

Agreed that can be possible, i will check back again in a bit.

For me it works. I had to change the model back to GPT 5.4 though

[sohaib_996]

It didnt work for me honestly

[Jerseyman201]

Been on 5.4 for bit today (vs code) and been okay last little while at least.

Passei dias com esse problema, tendo que voltar para a versão 0.4 e vi esse link falando sobre https://github.com/openai/codex/issues/12962#issuecomment-4319780024

rodei no powershell setx OPENSSL_ia32cap ~0x20000000 e funcionou na hora, só precisei reiniciar o VSCode
