These are super common images on HBT and elsewhere
Another secondary with massive headspace and an infection.
The problem is not the hops it's all the lovely air in the secondary vessel that you racked the beer to. Plenty for the microbes.
Secondaries should have as little headspace as possible to reduce oxygen availability and surface area for the ever-present airborne microbes.
Forget the idea of a CO2 blanket. It doesn't exist and the increased partial pressures of CO2 in the fermentor is gone the instant you rack the beer.
This looks infected for sure. You should post these great pictures in the post your
infection thread. Aside from the orientation they are really sharp. Thanks for posting them. Sorry for your loss.
