ArgumentException: Unknown Type#

  1. If you are trying to use aspects in a WithAll you should use WithAspect instead.
  2. Aspects may not be compatible with WithChangeFilter, target the individual components instead.
  3. If you are using generic components, you need to register each concrete type you use with [RegisterGenericComponentType].
