Browser cookies store information about your activity on YouTube Music. Corrupted or outdated cookies can sometimes cause issues. Clearing your browser's cookies and cache (if you're accessing YouTube Music via a web browser) might resolve the Error 400. If using the app, clearing app data, as mentioned previously, can have a similar effect.
