What's Wrong?

Every time I fire up claude desktop, the cowork section just doesnot work at all, but the chat and code tab (including in the terminal) work just fine, it keeps telling me "Failed to authenticate. API Error: 403 {"error":{"type":"forbidden","message":"Request not allowed"}}", i don't know hows that possible that only cowork queries get denied

What Should Happen?

process my queries and work
