I'd just like to point out to the many people pointing out the FTS activation that this is only the beginning of an answer unless you have an explanation for how the explosion drives an implosion.
The booster appeared to do an impersonation of the Titan submersible. Tank pressurization failed.
Not the first time we had a tank implode, in fact I believe the first high altitude starship flight failed when the fuel header tank imploded.
Edit: This very likely is a result of

Edit: This very likely is a result of FTS activation, visible in other cameras.
So @DutchSpace pointed out an airliner was flying through when the booster catch was supposed to happen, but it seems like it was never close to entering any of the TFRs
