Describe the bug

Fonts installation is Broken in Next js15.
I just create the app, and ran pnpm dev, first I got an error with turbopack saying see next dev for more information, but nothing on console so I just removed the turbo flag form dev command.

After that I am not able to get the fonts thing working.

Failed to compile

node_modules/.pnpm/[email protected][email protected][email protected][email protected][email protected]_/node_modules/geist/dist/sans.js
An error occurred in `next/font`.

Error: Cannot find module '....../whatevermyapp/node_modules/.pnpm/[email protected]/node_modules/@jridgewell/gen-mapping/dist/gen-mapping.umd.js'

I then tried google and local fonts with next/font/google and next/font/local, and nothing worked.

Reproduction repo

null

To reproduce

pnpm create t3-app@latest some-app

@IzaanAnwar If you need a quick fix you can try downgrading: "@jridgewell/gen-mapping": "0.3.5", manually. Also, make sure to remove node_modules and lock file(s).

So I tried to create a Normal nextjs app and it seems this error is there too.

Might be specific to my system. But still keeping the issue open, so that if others encounter the same, maybe someone can help
