[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：

But I was able to use it normally before, and suddenly this problem occurred. I didn't modify any configuration. Why is this happening?
