All of the sudden my NextJS app won't start or build, I get the following message:

I even checked out main branch and removed all local changes (few content pages and one form that should hit API to send data) to get back to previous state that worked, but it still doesn't work. I am on Win11 machine and have Node server running normally.
I had the same problem. Just delete the ".next" directory and run "npm run dev" that it will work again.
