Thanks for reaching out.
If AI extensions (Cline, Gemini, Codex, Deepseek, etc.) no longer show the chat panel on the left side, it’s usually due to one of these reasons:
- Extensions Disabled or Corrupted
- Go to Extensions (Ctrl+Shift+X) → check if they are enabled.
- If needed, uninstall and reinstall the problematic extension.
- Open Settings → search for chat or the extension name.
- Make sure the option to show the chat in the Activity Bar is enabled.
Pending Updates: Update VSCode and all extensions to the latest version. Restart VSCode after updating. **Extension Conflicts:**
- Go to Extensions (Ctrl+Shift+X) → check if they are enabled.
- Temporarily disable other extensions that might interfere.
- Test in a clean window using code --disable-extensions in the terminal.
- Authentication or API Key Issues
- Some AIs (like Gemini or Codex) require valid API keys.
- Check if credentials are correct in the settings or environment variables.
- Reset VSCode Layout Go to View → Appearance → Reset Layout.
- This often restores the missing side panel.
