Codex IDE extension stuck on ‘Loading…’ in VS Code and Cursor (Windows 11)

Hello,

I am having trouble with the Codex IDE extension in VS Code. The extension gets stuck on “Activating” and never opens.

Error/Logs:
In the Developer Tools console I see repeated warnings such as:

Could not read source map for … @microsoft/1ds-core-js/… .js.map

These seem non-critical, but the extension fails to finish activation.

Steps I already tried:

Reloaded VS Code window

Started with --disable-extensions (only Codex IDE enabled)

Cleared extension cache and reinstalled

Tested with a clean profile (–user-data-dir)

The issue still happens.

Could you please confirm if this is a known issue or provide guidance on how to resolve it?

Thank you.

Hi,
I was having the same issue, tried doing a clean install, reinstalling extensions, but then uninstalled ChatGPT Windows Store App, installed VC++ x86 and x64 (2015-2022) and reopened VS Code and it’s working now.
I am working on a Win11 machine.
