Review comment (refactor):
Could be better to unwind these a bit, to facilitate diagnosing any problem from the backtrace?
```suggestion
        page_props = self._search_nextjs_data(webpage, video_id)['props']['pageProps']
        stream = traverse_obj(page_props, (('liveStreamData', 'stream'), {lambda x: x['conf']['hls'] and x}, any))
        formats = self._extract_m3u8_formats(stream['conf']['hls'], video_id)
