HookWebpackError during `next build`

Hi! I've been trying to run npm run build since I'm slowly getting closer and closer to deploying my app. The traceback given by webpack only points to minified files which gives me no clue about where to even start debugging this. I've tried adding productionBrowserSourceMaps: true to my next config but that didn't help at all (produces the attached error). I'd be super grateful of any pointers of where to go next. If it is of any relevance (seeing as the error is a CssSyntaxError) I am using tailwind
