Can't use makemigrations - TypeError: can't compare offset-naive and offset-aware datetimes

I'm getting TypeError: can't compare offset-naive and offset-aware datetimes error when i run python manage.py runserver command

In the past i had a problem with timezones, i was using USE_TZ = True but changed it to False as suggested in this question. Not sure if they are releated but i have no idea what is the couse and how to fix this problem.
