That's a lot of speculation. We don't yet know why one of the Raptor engines failed to relight. The Raptor is a very new engine with only a handful of minutes of flight time. Keep in mind they also replaced a couple of the engines before the flight. I imagine SpaceX still be considers them development engines. You can also see some debris fly off of the bottom of the rocket just as it's performing its flip maneuver. With SN8 Musk tweeted casually about it, but he's apparently taking a hiatus for a bit.
