Hi all, I am trying to understand performance issues I get when I run great expectations task

from prefect_great_expectations import run_checkpoint_validation

My data is small and medium csv files. After debugging code step by step, I can see that GE prints results very quickly, in a few seconds, but then my code is stuck for a couple of minutes here `\Lib\site-packages\prefect\_internal\concurrency\waiters.py`:

def _handle_waiting_callbacks(self):
        logger.debug("Waiter %r watching for callbacks", self)
        while True:
            callback: Call = self._queue.get()
            if callback is None:
                break

All other non-GE tasks are fine here. I really don't know where to go from here and appreciate any help
