Same issue with Xcode 26.4 (17E192): Failed to authenticate. API Error: 401 {"type":"error","error":{"type":"authentication_error","message":"OAuth token has expired. Please obtain a new token or refresh your existing token."}"request_id":"req_..."}

Still unable. visionOS 1.0 Simulator is installed as a platform, but I can't select it as a run destination or add it to a target as a supported destination.
