Same error for DQN as well as DDQN

which version of gym are you using?

[dawmro]

Find your env.reset() and change it to: env.reset()[0]

Why? Look here:

(method) def reset(
    *,
    seed: int | None = None,
    options: dict[str, Any] | None = None
) -> tuple[Any, dict[str, Any]]

Another thing: If you are using gymnasium instead of gym, remember that done has been replaced with terminated, truncated. Addjust your functions accordingly.
