Hello @iyakov,
I doubt this would be the cause, but can you tell me which version you upgraded from? There is slim chance you might still have the old (deprecated) Generators package in your project. We (somewhat recently) moved away from having multiple packages. If that’s the case, please make sure the only package you have in your project is com.unity.ai.assistant. It is also fine to have com.unity.ai.inference and com.unity.ai.navigation.
