I also faced same issue, the issue is in "tailwind.config.js" file. when I give this command: "npx tailwindcss init -p" it gives me error. then I manually create both files: "tailwind.config.js" and "postcss.config.js". but still it didn't work. The issue was in the tailwind version, I had the new version of Tailwindcss. After that, I downgrade the version of Tailwind to "3.4.17" and run this command: "npx tailwindcss init -p". It works.
