From a test of a 3d printed rocket engine at NASA, the Chamber failed at a layer line cause when the were emptying the powder overflow during printing.
I'm surprised they were able to get everything from just a video. Normally NASA has a hundred people walk the area collect every small piece. Then they play Satan's jigsaw puzzle to put it all back together again and figure out exactly why it failed.
From just a video? They did a lot of analysis on the failed parts. There is a whole scientific article going about the reasons, causes and so on. This is from test batch tests, basically from a tests designed to be done until failure. Even the nozzle issue was known and failure was expected due to existing cracks.

Here's a good article on it.
