Edit project files without open it?

I need to edit idx.nix because I add a nix package since then I can’t open the project.
It’s building the environment for more than 30min

Yup sometimes it takes time reload the VM. You have to wait for a while and also close any live preview tab if opened.

More than 30mins I can’t open the project, I think that is bug since I add mongodb package try, if you build environment with the mongodb package this project can’t be opened more
