Scott Manley has already chimed in with his thoughts: Why Starship’s Booster Failed After Staging
It seems that several engines weren't just shutting down during the boostback burn, but were violently disassembling themselves. Possible cause could include propellant sloshing during the flip leading to inconsistent pressure fed to the engines/plumbing.
Gotta love how quick he is on these.
And he's now done a more in-depth analysis: Starship & Superheavy Become The Biggest Rocket In Space.... Before Exploding
He speculates that B9 engine failure during boostback was due to either fuel slosh, fluid hammer, or a combination of both. It's unclear whether the booster FTS was triggered or whether the Booster RUD happened on its own.
For S25, he notes that a puff of gas just after T+7 minutes coincides with a drop in the LOx gauge. This indicates an oxygen leak of some sort, which could have any number of causes.
