if I have a dev instance running and want to build the app with next build my app just crashes and the build doesn't go through...

if I refresh the dev server it says missing required error components, refreshing... and I am getting 500 Server Errors

maybe its because I am using --turbo

disabling it I can build the app while running it in dev mode but yet after I start to build and refresh my page I suddenly lose my styles (using tailwind)

any idea whats going?

both the dev server and the build process reads from and writes to the .next folder, so if you run both at the same time you can run into unexpected scenarios where the process sees something in .next that it doesn't anticipate

so: don't run both at the same time

ah ok that makes sense
can I change the output folder then?
or do they need to access the same output folder?

No I don’t think that’s possible
