I tried Developer: Reload Window again and the problem seems to have gone away for now.

I'm running into this same issue. Developer: Reload Window unfortunately did not work for me.

Some things to try:

1. Remove any expired root certificates from your machine.
   • This fixed a GitHub Co-Pilot issue for me.
2. Install the win-ca extension.
   • This fixed a GitHub Actions issue for me (almost**).
3. Close all open files and then do Developer: Reload Window.
   • There might be a bug where an open GitHub Action yaml file causes the extension to prematurely activate before the GitHub account context is ready.
4. Disable extension GitHub Actions. Then Restart Extensions. Then Enable extension GitHub Actions.

**Some of the steps above got me further, thought I am still experiencing issues with errors when hovering in the Action file.
