Codex chat window opens in sidebar when activated.

Additional information

The OS is Debian 12 KDE.

What steps I have tried:

uninstalled the extension, closed the VSCode, restart VSCode, retry opening the Codex chat window
uninstalled the extension, closed the VSCode, I have deleted the ~/.codex folder, restart VSCode, reinstall the Codex extension, retry opening the Codex chat window

What errors I get in the Output console of Codex:

can you try the workaround on the issues i opened: https://github.com/openai/codex/issues/34308 (also https://github.com/microsoft/vscode/issues/326580)

I kept getting this error

[warning] [CodexMcpConnection] cli: message="codex_core_plugins::manager: failed to load recommended plugins error=failed to send remote plugin catalog request to https://chatgpt.com/backend-api/ps/plugins/suggested: error sending request for url (https://chatgpt.com/backend-api/ps/plugins/suggested?scope=GLOBAL)"

What worked for me is to start with a clean VS profile, and disable apps and remote plugins in ~/.codex/config.toml:

...
[plugins."github@openai-curated"]
enabled = false
...

[features]
apps = false
remote_plugin = false

and then starting from a clean slate:

rm -rf /tmp/code-codex-clean
code --user-data-dir /tmp/code-codex-clean --disable-gpu

tested on Linux Mint 22 Cinnamon, VS 1.129.1, Codex 26.5715.61943

After a few days of not working, it seems to have fixed itself. After thta, I no longer see this issue anymore.
