Hi @David Thielen ,
For VS 17.10 or higher, GitHub Copilot(Chat and Completions) is built-in.
You can open VS Installer => Modify => Individual components and make sure that the "GitHub Copilot" component has been installed.
If it has been installed, please try to reinstall it(uncheck the option > Modify > check it again > Modify).
Best Regards,
Tianyu
