Followed the exact directions, doesn't open anything.

Followed these directions directly from the docs, step-by-step.

1. go to https://vscode.dev/ or use VS Code Desktop
2. install this extension from the market place: https://marketplace.visualstudio.com/items?itemName=ms-vscode.vscode-github-issue-notebooks
3. select "File > New File... > GitHub Issue Notebook"

No window opens, no window appears, nothing changes, nothing happens.
I have no "open" files or open repository. Just an empty window. Screenshot is from VSCode.dev
