DAIB preliminary notification (press release) is out; 3 out of 4 TR doors on the no. 1 engine did not stow when TOGA was applied.

Whilst the press release doesn’t say, one can maybe infer that the crew elected to go-around after deployment of thrust reversers. If TR were not selected by crew, and the doors “decided by themselves" to open asymmetrically on one engine only, that’s a whole different - and much scarier - scenario.
Press release doesn’t say why crew decided to go-around.
