What version of the IDE extension are you using?
openai.chatgpt-26.623.31921
What subscription do you have?
ChatGPT Pro
Which IDE are you using?
VS Code
What platform is your computer?

What issue are you seeing?
When I try to load a Codex editor with Codex: New Codex Agent, it shows:

I tried like hell to debug this to no avail (with help from ChatGPT web chatbot, ironically). ChatGPT 5.5 high eventually say:
At that point, treat this as an OpenAI Codex VS Code extension bug with version: openai.chatgpt-26.623.31921
It is only when I downgraded to VS Code Codex Extension version 26.616.32156 that the agent seems to load and work correctly.
What steps can reproduce the bug?
Install VS Code version 1.126.0 and Codex extension version 26.623.31921 and give it a shot.
What is the expected behavior?
I expect the Codex agent window to open and work.

I second that! Can't even show it as the default open anymore.
Same problem with most recent version
26.623.42026. I will try to find the most recent version where this does not happen.I bounded the error between the two consecutive releases:
26.616.81150: Broken26.616.71553: Works!I will be sticking with
26.616.71553for the forseeable future.Can I just say that it is a bit shocking that a frontier AI company that builds AI coding tools does not have a quality AI-based bot (based on Codex) that can automatically triage GitHub issues like this and automatically reproduce the failures (if not fix them). It seems that a company like this could really show off their models and tools when implementing a process like this. What does this say about the current real state of AI tooling for software engineering if the frontier AI companies can't even do this with their own AI-based products? Seems like a huge missed opportunity to sell this stuff.
Same problem other AI SWE-focused projects like OpenCode. Bug reports on GitHub are completely ignored. What is going on with this?
This makes me think that AI-based tools that can actually automate software engineering are a long ways off.
Is anyone else with me on this?
For weeks now, the same thing occurs for me on all 3 of my computers, Windows, MacOS or linux. Ive tried everything from renaming .codex folder to removing codex extension and CLI completely from the machines.

Going back to 71553 as mentioned above does not fix it for me.
I am a new OpenAI Codex customer who installed the VS Code extension in a devcontainer for the first time and immediately rang into an extension hang bug. Downgrading to 26.623.141536 fixed the issue (although GPT 5.6 is not an available model). Please fix

FYI: My workaround was to just install the Codex CLI in my container and run it from a VS Code terminal. I don't think that TUI UI is as nice as the VS Code Codex extension, but at least I can use the GPT 5.6 models. I guess we are stuck with TUIs for coding agents going forward (which is not all bad from a security perspective).
