[Python] django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet

When I add in the configuration of logging I get this error

Traceback (most recent call last):

If I do not specify any logging settings, runserver runs fine. Logging settings:

LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'verbose': {
'format': '%(levelname)s %(asctime)s %(module)s %(process)d %(thread)d %(message)s'
},
'simple': {
'format': '%(levelname)s %(message)s'
},
},
'filters': {
'special': {
'()': 'project.logging.SpecialFilter',
'foo': 'bar',
},
'require_debug_true': {
'()': 'django.utils.log.RequireDebugTrue',
},
},
'handlers': {
'console': {
'level': 'INFO',
'filters': ['require_debug_true'],
'class': 'logging.StreamHandler',
'formatter': 'simple'
},
'mail_admins': {
'level': 'ERROR',
'class': 'django.utils.log.AdminEmailHandler',
'filters': ['special']
}
},
'loggers': {
'django': {
'handlers': ['console'],
'propagate': True,
},

'level': 'ERROR',
'propagate': False,
},
'myproject.custom': {
'handlers': ['console', 'mail_admins'],
'level': 'INFO',
'filters': ['special']
}
}
}


Tried other logging settings as well, but still the same error
