Foundation Model Always modelNotReady

I'm testing Foundation Model on my iPad Pro (5th gen) iOS 26. Up until late this morning, I can no longer load the SystemLanguageModel.default. I'm not doing anything interesting, something as basic as this is only going to unavailable, specifically I get unavailable reason: modelNotReady.

        let model = SystemLanguageModel.default
...
        switch model.availability {
        case .available:
            print("LM available")
        case .unavailable(let reason):
            print("unavailable reason: ", String(describing: reason))
        }

I also ran the FoundationModelsTripPlanner app, same thing. It was working yesterday, I have not modified that project either.

Why is the Model not ready? How do I fix this? Yes, I tried restarting both my laptop and iPad, no luck.
