Solutions

1. Select a model/provider in the chat or session settings before sending a message.
2. If settings were restored from a backup or older version, re-pick the model so settings.provider is populated.
3. Check that no code path constructs SessionSettings without a provider field.

Example fix

const provider = setting.provider
if (!provider) {
  // Open the model selector and choose a provider for this session
}
