      Name of Failure:

      test.test_transactions_unified.TestUnifiedMongosUnpin.test_unpin_after_TransientTransactionError_error_on_abort

      Link to task:

      https://spruce.mongodb.com/task/mongo_python_driver_tests_python_version_rhel8_test_ssl__platform~rhel8_auth_ssl~auth_ssl_python_version~3.12_coverage~coverage_test_4.4_sharded_cluster_af2d56c5b508003d564c25433613200583cb15d7_24_03_04_19_55_00?execution=0&sortBy=STATUS&sortDir=ASC

      Context of when and why the failure occurred:

      Occurring randomly starting with PYTHON-4243, which was an EVG config-only change.
      It seems to only occur on 4.4 and latest.
