To Reproduce

Hello everyone, i'm using Turbo in the developer environment nextjs14, but I'm getting the following error. Has anyone encountered this error?

Note: When I get this error that NEXTjs wants to render my routes.

}

Current vs. Expected behavior

When I use Turbo, this problem occurs and the fonts of my site do not load and the application does not work properly and it also gives this error, but without Turbopack there is no problem, the application works properly.

same issue. Tried deleting the .next folder but didn't work. Sadly couldn't create a reproduction repo as I have a lot of code.

Fonts loaded by next/font/local returns 404 too.

Same issue here. for now, i just removed --turbo.

[tbenci]

Adding --turbo is the main reason we've upgraded. NextJS is a slow old pig and need speeding up. If --turbo is not working why bother.

[enricoros]

Same here. I'm using the JetBrains IDE - does it have anything to do with this? Agree: --turbo is the reason to upgrade to NextJS 14 for me..

Is anyone running into this on an OS other than windows?

It's hard for us to reproduce without being on windows

[ForsakenHarmony]

Doing some research, this is a problem with windows specifically.

See: https://github.com/libuv/libuv/pull/1981

Antivirus might be locking the file preventing it from being renamed

So this isn't really a next.js bug, but we can add a retry to work around broken windows behaviour

I will check again

Hi Vercel NextJS team,

This is very frustrating. I installed NextJS onto a bare bones Windows 11 machine with AVG antivirus. That's about it.

I have been working with NextJS for a while without any issues.

When I try to use --turbo, it doesn't work.

Obviously it is working for others but, it is also not working for others.

I am happy to do what every you suggest to try to fix this so tell us what to do.

Just saying it "might be antivirus" doesn't help much. What does that mean and what do we need to do to fix it.

A bit of direction would be most appreciated because all I can tell those that ask me is that --turbo doesn't work.

I tried it on my work machine on a completely different network, IP provider etc. and still it does not work.
