Failure to retrieve username: Ls [HttpError]: fetch failed

**Describe the bug**
When I am editing a workflow file, and my mouse moves, I get an error box pup up repeatedly. It can pop up several times over the course of a single pointer movement down the file.

**To Reproduce**
Steps to reproduce the behavior:
1. Edit any workflow file
2. Hover over any any of several steps/components of the workflow
3. See error


When the popup occurs, I get this in the OUTPUT tab:

```

I tried following the advice in https://github.com/github/vscode-github-actions/issues/282, but that did not help. However, after disabling GitHub Actions, restarting Extensions and enabling GitHub Actions, I got this similar error in the OUTPUT (only differences posted):

```

**Additional context**
macOS Sonoma 14.7
The GitHub Actions activity bar icon works fine
