Bug: Litestar Logging in Python3.12: Unable to configure handler 'queue_listener' (Pycharm Debugger)

[Rey092]

Description

Same as #2469
But only for pycharm debugger. Regular runner works fine.

URL to code causing the issue

No response

MCVE

from litestar import Litestar, get


@get("/")
async def index() -> str:
    return "Hello, world!"


@get("/books/{book_id:int}")
async def get_book(book_id: int) -> dict[str, int]:
    return {"book_id": book_id}


app = Litestar([index, get_book])

Steps to reproduce

1. Python 3.12
2. Run MCVE with pycharm debugger

This is not a bug in Litestar, but in Python 3.12.4, which introduced breaking changes in the logging module with python/cpython#120030.

As a workaround you can stick to a Python version that doesn't have the bug (3.12.3 should work) and wait until 3.12.5 comes out with the fixes.

See also #3591.
