The instruction `varinfo()` does not work when calling it from code file in VSCode, I had to load manually `InteractiveUtils` and then execute the function, but the objects `global_err_handler` and `is_disconnected_exception` are created:

This does not happen if I try the same directly in the Julia REPL, without even having to load `InteractiveUtils`:

**Any ideas of what is going on and how to fix it?**

The REPL automatically loads `InteractiveUtils` for you. If you need it outside of that context, you should load it manually.

I have been using Julia in VS Code for a while, and it was just until today that I had to load it manually.

You don’t have to unless something is broken, here’s what I just did in a fresh VSCodium session:

This is a recent regression afaict.

Ha, indeed, ignore my comment - just restarted VSCodium and now I see the same issue, I was probably on an older version of the extension.
