On the first test run, there is only one real failure (mypy). The second failure at

 ======================================================================
FAIL: test_session_attendance (ietf.meeting.tests_views.ProceedingsTests.test_session_attendance)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/__w/datatracker/datatracker/ietf/meeting/tests_views.py", line 9323, in test_session_attendance

    self.assertTrue(

is a transient.
The rest are just consequences of the first two.

For the first error, try

HistoricalReviewAssignment = ReviewAssignment.history.model

just before using it in the code rather than importing HistoricalReviewAssignment.
