`isinstance` doesn't work with `TypeAlias` for classes inherited from `NamedTuple`

Bug Report

isinstance throws Parameterized generics cannot be used with class or instance checks [misc] for TypeAlias for a class inherited from NamedTuple. This is related to https://github.com/python/mypy/issues/18488

To Reproduce

from typing import Any, TypeAlias, NamedTuple

class Foo(NamedTuple):
    pass

Alias: TypeAlias = Foo

def is_foo(x: Any) -> bool:
    return isinstance(x, Alias)

Actual Behavior

• Mypy version used: 1.19.1
• Mypy command-line flags: mypy . --strict
• Mypy configuration options from pyproject.toml:

[tool.mypy]
strict = true
allow_redefinition = true
allow_redefinition_new = true
local_partial_types = true
follow_untyped_imports = true

• Python version used: 3.13.11

Start with the provided NamedTuple, TypeAlias, and isinstance reproduction in mypy-play, using mypy 1.19.1 with Python 3.13 and strict settings. Trace the diagnostic that reports parameterized generics in class or instance checks, then confirm the fix by rerunning the reproduction and verifying that no error is reported.
