Django 5.1: ImportError: cannot import name 'get_storage_class' from 'django.core.files.storage'

When I tried to use django-storages with Django 5.1 I have got following error:

Traceback (most recent call last):

The error message by the OP is not for django-storages but wagtail_storages. I am having the same error. This is marked as fixed, but I just installed the below and am getting the below error. I must admit that the messaging here is rather terse. the fix linked above rererences commit
451fcbe
which does not exist on the repo for wagtail storages repository linked in the github issue above:
#50
which says the solution is:
451fcbe
which is an update to a KVPair in a YML file.
