Done.
Install of VS Codium to replace VS Code went nicely (via 'snap' in Ubuntu's 'App Center').
Needed only to reinstall a couple of extensions and reconnect to github (which is another service for which like to review alternatives).
Also took the opportunity to install a 'linter' (Ruff) for superficial code review - it's a helpful tool; learned about the risk of 'bare excepts' which are ubiquitous in online code snippets/advice.
