GitHub Actions extension fails with "Unable to connect to the GitHub API" in .code-workspace (works with Open Folder)

[paul-michalik]

Description

When I open the same repository via a multi-root .code-workspace, the GitHub Actions extension shows:

Unable to connect to the GitHub API, please check internet connection

If I open the repository directly with File → Open Folder, the extension works normally (workflows/runs load, authentication is fine).

This appears specific to workspace-mode repository resolution/activation, not network connectivity.

Steps to reproduce

1. Create/open a multi-root workspace that includes this repo as a root:
   • c:\Users\<user>\Source\loom-workbench (plus other roots in workspace)
2. Open VS Code using the .code-workspace file.
3. Open the GitHub Actions view.
4. Observe error: "Unable to connect to the GitHub API, please check internet connection".
5. Close VS Code.
6. Reopen only c:\Users\<user>\Source\loom-workbench via Open Folder.
7. GitHub Actions extension works correctly.

Expected behavior

The extension should authenticate and connect to GitHub API the same way in both:

• Open Folder mode
• .code-workspace (multi-root) mode

Actual behavior

• Open Folder: Works
• .code-workspace: Fails with API connection error
