Research direction
Investigate the cipher manifest extraction logic in the codebase, likely in files related to YouTube downloader's signature deciphering. Check for recent changes in YouTube's API that may have broken the extraction. Look at the issue comments for any hints from other users or maintainers about workarounds. Consider implementing a fallback method or updating the cipher extraction algorithm.
