Non-idempotent computation

Describe the bug I receive very often a fatal IDE error.

This plugin searches pydantic dataclass from all python objects. Libraries often use pydantic models. So checking all objects in the library.

I don’t see an error. But, Django is a huge framework. The searching way might not correct.

I will check a better way.

Yes, this class is from Django package (web framework). It’s a regular python class, even not a dataclass. Strange. How your plugin connected to it?
