VS Code extension: file links no longer open in editor

What version of the IDE extension are you using?

26.409.20454

What subscription do you have?

Plus

Which IDE are you using?

VS Code

What platform is your computer?

Microsoft Windows NT 10.0.26200.0 x64

What issue are you seeing?

File links in chat responses no longer open files in the VS Code editor.

In Codex extension v26.406.40811, links like:
[file.yml:5](/home/user/file.yml#L5)
opened the target file in VS Code at the correct line.

In v26.409.20454, the same links no longer open in the editor. Right-click only shows:

• Copy path
• Open in File Manager

This happens on Windows 11 with VS Code 1.115.0, with the Codex extension installed in WSL.

What steps can reproduce the bug?

1. Install the Codex extension in WSL.
2. Open a workspace in WSL
3. In Codex chat, ask Codex to reference a local file with a file link, for example:

[file.yml:5](/home/user/file.yml#L5)

1. Click the link in the chat response.
2. Downgrade the extension to v26.406.40811 and repeat the same steps.
3. The file opens correctly in the editor in the older version.

Result:
The file does not open in the VS Code editor.

Additional observation:
Right-click on the link only shows:

• Copy path
• Open in File Manager

What is the expected behavior?

File links in Codex chat responses should open the target file in the VS Code editor and jump to the referenced line.
