Npm run dev error: package.json invalid path

Bugs
1

Hi, I just signed up for Builder, I’m on “Welcome to Builder” screen, using “Integrate your existing project”, and I get error when starting dev server: Error: Invalid path: C:\dev\project\code\package.json (7341) when executing npm run dev on Windows

Detailed steps to reproduce the bug
I created a new Qwik site using Cloudflare Pages integration following Deploy a Qwik site · Cloudflare Pages docs.
Then, I signed up at builder.io and got to the “Welcome to Builder” screen that said to run npm init builder.io@latest --existing to “Integrate your existing project”.
After that, I ran npm install and npm run dev, but it errors out right away with the following:

> dev
> vite --mode ssr

error when starting dev server:
Error: Invalid path: C:\dev\project\code\package.json (7341)
    at m (file:///C:/dev/project/code/node_modules/@builder.io/dev-tools/node/index.mjs:1:2907)

    at async CAC.<anonymous> (file:///C:/dev/project/code/node_modules/vite/dist/node/cli.js:762:24)

These are the dependencies added:

    "@builder.io/dev-tools": "^0.2.19",
    "@builder.io/sdk-qwik": "^0.14.3"

And it fails here:

if(!o.startsWith(n))throw new Error(`Invalid path: ${o} (7341)`)

n: 'C:/dev/project/code'
o: 'C:\dev\project\code\package.json'

Is there a way to make sure it uses the normalized slashes in both cases?
