最新版本

是qq等的url源失效了吗？

Check the source code for music providers, likely in a directory like 'providers' or 'sources'. Look for changes in the UI or configuration that removed QQ, KuGou, etc. Test the search function to see if it still returns results from those platforms, and verify if their API endpoints are still reachable. The goal is to understand why only NetEase is shown and whether other sources can be restored.
