Broken build on `9.5.4`

See original GitHub issue

Bug report

Describe the bug

After upgrading to 9.5.4 from 9.5.3, next build is no longer working for me. I’m also using tailwindcss@1.8.12 + postcss.

To Reproduce

# Running on `9.5.3` (works fine)
yarn dev

$ cross-env NEXT_TELEMETRY_DISABLED=1 NODE_ENV=development next -p 8090
info  - Loaded env from /dev/project/.env.local
ready - started server on http://localhost:8090

risk - There are upcoming breaking changes: removeDeprecatedGapUtilities, purgeLayersByDefault
risk - We highly recommend opting-in to these changes now to simplify upgrading Tailwind in the future.
risk - https://tailwindcss.com/docs/upcoming-changes
event - compiled successfully

# Upgrade to `9.5.4` and try again
rm yarn.lock
yarn add next@latest
yarn dev

$ cross-env NEXT_TELEMETRY_DISABLED=1 NODE_ENV=development next -p 8090
info  - Loaded env from /dev/project/.env.local
ready - started server on http://localhost:8090

Then it starts looping on a `MODULE_NOT_FOUND` exception

Expected behavior

Build should continue to work. No other change was introduced in the failing project.

Reverting back to 9.5.3 solves the issue.
The file it’s complaining about (/fonts/la-brands-400-98099f67.eot) it’s actually there and has always been.
next build fails with the exact same error.
