I have just started learning Next.js but I tried npm run build because I saw you can also use that but now I cant use next, nothing loads or updates any more, how do I undo Build mode

What are you trying to do?
You run next start after npm run build to open the app. All the changes after this will not update unless you run npm run build again.

During development, you should run npm run dev to get smooth update and only run build and run start when you wanna see production build.

Concluesion:
npm run dev
- use it during development (while ur building the app)
- fast refresh (hot reload) & live updates
- slower performance because it's not fully optimized

npm run build + next start (or npm run start)
- optimized version so it's faster
- no hot reload
- you can't see changes without rebuilding again and run start again.
