Current set of migrations results in the stack trace below with django==4.0a1, if I recreate the migrations they work like charm.

./manage.py test
Found 96 test(s).
Creating test database for alias 'default'...
Traceback (most recent call last):

    return Database.Cursor.execute(self, query, params)
sqlite3.OperationalError: table new__app_occupation has no column named boolean

The above exception was the direct cause of the following exception:
