AssertionError: trying to find dataclass transform spec

Bug Report
mypy crashes on the example below instead of showing an error or not showing anything.

Encountered today while refactoring a pretty big codebase. Made an accidental mistake, hence the @dataclass(frozen=True)(kw_only=True), but the way Mypy fails won't allow me to find the culprit. I couldn't find a way to debug what was causing an error (--pdb option didn't work for me).

To Reproduce

from dataclasses import dataclass


@dataclass(frozen=True)(kw_only=True)
class Foo:
    bar: str

Expected Behavior
Correctly identified error in the code, or at least no crash

Actual Behavior

AssertionError: trying to find dataclass transform spec, but reason is neither dataclasses.dataclass nor decorated with typing.dataclass_transform

Your Environment

• Mypy version used: 1.5.1 (also tried most recent from git, same)
• Mypy command-line flags: None
• Mypy configuration options from mypy.ini (and other config files): None
• Python version used: 3.11.5

Reproduce the crash with the dataclass example and start in mypy/plugins/dataclasses.py, especially dataclass_class_maker_callback and _get_transform_spec from the traceback. Check how the malformed @dataclass(frozen=True)(kw_only=True) is handled; done means mypy reports an error or completes without an AssertionError.
