The engine did shut off. the flame was from something burning. SN5 also experienced a small fire on the engine. This issue needs to be sorted out.

It's probably raw fuel rebound. When rockets take off they actually can spew out raw fuel before the igniter kicks in. That hits the ground with force splashing back into the area around the rocket engine.

You can see it in the first few seconds of this video

I don't see any smoke coming from the rocket itself whether going up or down, so where is all that smoke coming from?
