The time between boosters first being reused in Falcons and this mission is the same as the time between JFK's 'we choose to go to the moon' speech and the actual moon landings.
(What's the most valuable payload NASA has lost during launch? Apollo 1 wasn't launching, nor were the space shuttles.)
NASA and the FAA were pretty clear on this actually, they don't see any risk due to that previous failure, falcon 2nd stages haven't had any problems with their primary burn in a long time.
I had misremembered: it was the Hera launch the FAA cleared because there was no reentry risk. Europa clipper was expected to get the same treatment, but it seems the FAA and SpaceX were happy with their understanding of what happened with the 2nd stage anomaly and returned Falcon 9 to flight. [3]
