Thank you so much.
The error is

mypy: commands[0]> mypy flask_jwt_extended/ tests/
flask_jwt_extended/tokens.py:103: error: Argument "options" has incompatible type "dict[str, bool]"; expected "Options | None"  [arg-type]
Found 1 error in 1 file (checked 30 source files)

The corresponding lines are

    decoded_token = jwt.decode(
        encoded_token,
        secret,
        algorithms=algorithms,
        audience=audience,
        issuer=issuer,
        leeway=leeway,
        options=options,
    )  

That might be due to imcompatible change of pyjwt.
