Got similar error. My case is Win 10 and fresh boilerplate Vue project from this repo.

As I can see the issue happens in transformGlobImport method at node_modules/@fastify/vite/node_modules/vite/dist/node/chunks/dep-5605cfa4.js:35470, but I have no understanding how it can be fixed.

There's a row let importPath = relative(dir, file) in this method, where relative is POSIX method (defined in a code above).
Finally for

dir='/'
file='C:/Users/myusername/projectname/client/pages/client-only.vue'

I get

importPath='Users/myusername/projectname/C:/Users/myusername/projectname/client/pages/client-only.vue'

Right now after number of hours I found that it works with

let importPath = path$o.relative(dir, file);

instead of

let importPath = relative(dir, file);

(where path$o.relative is cross-platform node:path method). But I don't know yet how to prepare this in PR.
