Apache + mod_wsgi + Django + dataclasses stopped working after upgrade to python3.10

After upgrading to python3.10 code with dataclasses stopped working with mod_wsgi.

If a class is created with @dataclass decorator (with just a single attribute x: str) and then instantiated somewhere in apps.py at module level, an exception is thrown. The reason is missing generated __init__ method (I confirmed that everything works if I define __init__ manually). Unfortunately, in real project it's part of external library and dataclass is instantiated in imported module, so there's no way to define __init__ by hands. The code without changes (all packages have same versions too) works with python3.9.

To be clear, here's the code:

# models.py
from dataclasses import dataclass

@dataclass
class Test:
    foo: str

# apps.py
from django.apps import AppConfig
from .models import Test

Test('bar')  # Error is thrown here

class AppConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'app'

It seems like there's a bug somewhere. I also know that mod_wsgi only support python up to 3.8, according to data on pypi, but can't believe the answer is "Look for other wsgi solution or don't upgrade yet" (if so - tell me too, it might be true). You might notice that Django is of version 3.2 in requirements while 4.0 is available: I tried upgrading on this demo project, nothing has changed, plus django 3.2 claims to support python3.10 too (on the real project I can't upgrade due do dependencies using deprecated functions). So my questions are:

1. Am I missing something that should be changed on upgrade to python 3.10 in this case?
2. If it's some inner bug, where should I report it --- to python 3.10, to mod_wsgi or to Django?

The traceback is:
