Copilot code completion don't work.

**Versions**
- Copilot for Xcode: [e.g. 0.25.0]
- Xcode: [e.g. 16.2]
- macOS: [e.g. 15.1.1]

question description:
After being prepared according to the official documentation, it worked normally for the first few days, and now suddenly **code completion** does not work.

github-copilot-for-xcode.log
**[GitHubCopilot] [56586] Try getting suggestions again: Language server error: Server error: -32603 rate limited nil**

my guess:
Does the free version of copilot for xcode also have a 2000 code completion limit?
