Initial Checks
Description
On python 3.12.0 - 3.12.3, the recently released pydantic-1.10.20 doesn't work with forward ref type annotations.
Downgrading to pydantic-1.10.19 does not throw the exception.
Potentially related to #9609
Example Code
from pydantic import BaseModel
class Schema(BaseModel):
test: "Foo"
Foo = str
