I got same issue few days back, I removed the styles from folder and added it to app directly. it got fixed for me:)

Thank you for the help so far. Please can you send screenshots of how you did it. I still couldnt figure it out. Thank you

I figured it out, thank you. I had to make adjustment to the globals.css file based on the new tailwind 4 specifications.
