Hey all, anyone had issues just running the most basic test with prefect?

from prefect import flow
from prefect.testing.utilities import prefect_test_harness


@flow
def my_favorite_flow():
    return 42


def test_my_favorite_flow():
    with prefect_test_harness(server_startup_timeout=120):
        assert my_favorite_flow() == 42

I seem to be unable to make it work, I always get a 'timeout':
