Reproduction of the bug/regression with instructions

On the first ng serve after npm ci the application crashes with the following error:

Hi @ladler1

I'd like to know a bit more about the context, a small repo that shows the issue would be nice. But these are the things i am particularly interested in.

• What commands are you using when you startup your project? (only npx ng serve?)
• Is this the host of a micro frontend?
• Are you using Nx, SSR, SSG or anything else?
• Does this happen if you run a single project or multiple projects concurrently?
• Is your workspace a monorepo or polyrepo?

[Aukevanoost]

If you want to help and re-create the issue, but cant share your current repo. here are some starter repo's:

• https://github.com/Aukevanoost/native-federation-examples-ng
• https://github.com/manfredsteyer/mf-nf-poc/tree/main
• https://github.com/manfredsteyer/nf-test (for frameworks)

You can check it out and start adding configuration similar to your setup to see what breaks the setup. This helps us a ton to investigate what went wrong :)

Hi thanks a lot @Aukevanoost . I will try as soon as possible to recreate the issue with one of your demo repos.

This seems like exactly the same as #970
; especially interesting is the stacktrace, and the proclaimed problem locating vite.
What strikes me as odd is the path with '' instead of '/', and the missing '' after node_modules in the exception message.
I don't know yet if this means something, but it's sure odd.
