vite Build fails when running in mapped Windows network drive (UNC issue)

Describe the bug

Running vite or vite build in a network drive results in error, it seems that the path gets magled by including the UNC representation of the mapped drive.

Setup:

Windows 11
mapped RedactedServer to my K: drive

Everything works fine if I move all the project to the C: drive (eg. C:\Users\MyUser\Downloads\test)

error during build:
[vite:load-fallback] Could not load /RedactedServer/Projects/test/index.html: ENOENT: no such file or directory, open 'K:\RedactedServer\Projects\test\index.html'
    at async open (node:internal/fs/promises:636:25)
    at async Object.readFile (node:internal/fs/promises:1246:14)
    at async Object.load (file:///K:/Projects/test/node_modules/vite/dist/node/chunks/dep-NjL7WTE1.js:64965:25)
    at async PluginDriver.hookFirstAndGetPlugin (file:///K:/Projects/test/node_modules/rollup/dist/es/shared/node-entry.js:19792:28)
    at async file:///K:/Projects/test/node_modules/rollup/dist/es/shared/node-entry.js:18956:33
    at async Queue.work (file:///K:/Projects/test/node_modules/rollup/dist/es/shared/node-entry.js:20002:32)

K:/Projects/test becomes /RedactedServer/Projects/test which is the correct UNC representation, but K:\RedactedServer\Projects\test\index.html is searched, which doesn't exist

Steps to reproduce

# in a windows mapped network drive

I have the same issue. It was working before and I came back to the project after maybe two months and now it doesn't. I didn't change anything but I don't control the OS. It's a VM controlled by my employer. So it might have something to do with a Windows update.

Same here, even with mapped drive D:\ pointing only into C:\Users\<UserName>\Work, which is just a folder in my local PC's local SSD, on the local C:\ drive.

The workaround here or here solved me though.
