Due to a circular import, the AnyComponent alias is imported in an if TYPE_CHECKING: block in fastui.components.forms:

and later used in one of the defined models for this module:

While this used to work in <2.10 because of namespace pollution inconsistencies, it doesn't with 2.10 as AnyComponent (which doesn't exist in the module namespace at runtime) isn't available.

Best way forward would be to fix the circular import, haven't found a viable implementation yet.
