If a student recorded anything before getting locked out of a single attempt question, whatever was recorded should be be submitted to the instructor.
There are still scenarios where a students could get locked out before recording anything. For example, if students open a single attempt question and close the page, lose WiFi connection, or turn off the device. This would continue to be a Locked Attempt.
Question to consider:
If a recording is captured when the students would have otherwise been locked out should this appear in Grading as locked or submitted?
