interactive: Not getting a notebook interface when I create a .dib file in Visual Studio Code Insiders

Describe the bug

I’m following the steps for enabling .NET Interactive notebooks in Code Insiders, and I cannot get a notebook interface.

1. Installed Code Insiders
2. Installed PowerShell Preview extension (tried with the stable version too)
3. Installed .NET Interactive notebooks extension
4. Created a new file and saved it with the extension .dib Nothing happens.

If I try to open .dib file created by someone else, I get the “Unable to open ‘test.dib’: Cannot read property ‘message’ of undefined.” error message. If I disable PowerShell extension, I can at least open test.dib file as a textual file.

Please complete the following:

Which version of .NET Interactive are you using? There are a few ways to find this out:

• In VS Code, run "Report installed version for .NET Interactive` and copy the version number from the status popup.

That command doesn’t exist.
