Does deleting .next and retrying dev/build do the trick, right?

[spirosikmd]

I tried that, and it doesn't! 😕

[icyJoseph]

😞 - could it be some syntax in the SASS file? a selector? declaration? Good old, delete stuff until it works

[spirosikmd]

Even if I comment out all our content in the AppLoader.module.scss file, I still get the same error.

Does this [ssr] part indicate something specific?

Not sure, do you think you could setup a small reproduction example? Was it working with previous Next.js versions?

[spirosikmd]

First of all, thank you for the immediate feedback! 🙌

I haven't tried Turbopack in previous versions of Next.js. Is it worth doing that?

I can set up a small reproduction example, but I am not sure if I will succeed. 😅 The app I am trying this on is large and slightly complex. So, it could be anything in this app. I had to make many changes already to reach this point and encounter this error.
