[v4] @tailwindcss/postcss returns error on windows x64

[Mankindofficial]

Got this error while starting up my dev server after using the upgrade to v4 command

[Failed to load PostCSS config: Failed to load PostCSS config (searchPath: C:/Documents/TailwindProj): [Error] Loading PostCSS Plugin failed: Cannot find module 'C:\Documents\TailwindProj\node_modules@tailwindcss\oxide-win32-x64-msvc\tailwindcss-oxide.win32-x64-msvc.node'. Please verify that the package.json has a valid "main" entry

Any clue or advice would be very much appreciated.

The error indicates a missing native module. Try reinstalling Tailwind CSS and its dependencies, checking Node.js version, verifying tailwind.config.js, and reinstalling native modules. Login & Support
