Exact same issue. I upgraded claude to a paid tier and tried installing the plug in into Excel on Mac OS but it gives me the same error as the rest. tried uninstalling, remove cache, keychain passwords switching accounts but no luck. I was about to call Microsoft but seems like they are not of much help. I hope they push out an update soon
