[Bug] Anthropic API Error: 500 Internal Server Error on all prompts

Bug Description
whatever I write any prompt I got respond :API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server error"},"request_id":"req_011CXZhg6D1j4XVpvyY8nHyM"}

even I logout and login, kill the terminal and reopen it, it's not working correctly.

almost 5 minutes ago, I got always API Overloaded error. Now, I got API Error:500.
