If the previous crew had been in that position they would have taken steps to preserve the data by pulling the CB and making a tech log entry to that effect, the CVR will be either be downloaded or pulled and replaced before the aircraft is dispatched again.
GroundedSpanner sums it up perfectly.
Could be anything relevant to flight safety. Maybe something should have been reported but wasn't. You do not know.
There have also been many instances of crew forgetting to preserve the CVR/FDR so just saying they would do so is factually wrong.
But, again, you crack on.
