NX GitHub Copilot chat participant issue

[vrxj81]

Current Behavior

Hi, I am using VS Code with GitHub Copilot, but it seems the NX extension for Colpilot isn't refreshing the workspace. I deleted a project with the NX CLI and when I use @nx in the GitHub Copilot chat it errors out, displaying deleted files from the deleted project.

Expected Behavior

using @nx chat participant in Copilot chat works

2. mention @nx participant in chat and ask anything

Additional Information

I first used MikroORM with the backend app and libraries. Then refactored to TypeORM. I don't exactly know when the issues with the chat participant started. I have it in another workspace as well.
Firstly I had the same error message in the Problems View and Nx Projects View, but they went away after refreshing the workspace from the Nx Console. The errors do persist in the Copilot chat however

it works for me... looks like you got into some weird state there. Did you run `nx reset`? And if that doesn't work, delete and reinstall node modules?

Hi Max, thanks for taking a look.
I have tried nx reset and reinstalling node modules already.
I’m going to try a reinstall of VS Codium

@MaxKless reinstalling doesn’t solve it.
Any idea where I might look?
