[Bug][BLOCKER] Anthropic API Error: Invalid OAuth token authentication failure

[theReallyRealDusty]

Bug Description I keep getting "API Error: 401 {"type":"error","error":{"type":"authentication_error","message":"Invalid OAuth token. The provided token was not found or is malformed."},"request_id":"req_011CVQuYJVPnBVuNiZ8apzdk"} · Please run /login "

/login works but it doesn't actually solve the problem. I can just continue and it will run for a bit and then stop with this error again. This is a 100% blocker since it interrupts all sessions.
