[Method 1] After enabling Apple Intelligence, I can log in to ChatGPT but it does not work properly

### Additional Information When I use chatpgt in Xcode, it shows the error as follows： <img width="386" height="790" alt="Image" src="https://github.com/user-attachments/assets/0b4c21b0-63c9-4d1b-9aba-7c5c02e90eaf" /> But I was able to use it normally before, and suddenly this problem occurred. I didn't modify any configuration. Why is this happening?
