…sion (#71696) A Dag run can have no version of its own: runs carried over from Airflow 2 predate the version columns, and `airflow db clean` can remove the version a run was created with. Clearing such a run left its tasks without a version too, and a task instance with no version is never enqueued — so the task sat in queued until it timed out, while its revived run held up new ones. The clear dialogs offered no way out either, since they only showed the run-on-latest option when there was a version to compare against.

A Dag run can have no version of its own: runs carried over from Airflow 2
predate the version columns, and
airflow db cleancan remove the version arun was created with. Clearing such a run left its tasks without a version
too, and a task instance with no version is never enqueued — so the task sat
in queued until it timed out, while its revived run held up new ones. The
clear dialogs offered no way out either, since they only showed the
run-on-latest option when there was a version to compare against.
