Oh I'm so, so sorry. That's awful, and so sudden. I hope you guys are alright, this is always so difficult to get through...
It does sound very much like an egg either ruptured inside her, causing internal bleeding and possibly peritonitis, or she was actually egg-bound. The black beard indicates sudden pain, and the bloating is also a sign of internal bleeding or infection. Sometimes the vets can't always see all the eggs on a flat x-ray, and sometimes the eggs develop quickly. I've seen several breeder parrots thathad become egg-bound, and it sounds just like it. It's typically sudden, painful, and unless you're aware of it and can intervene (much easier to help a parrot than a bearded dragon) they die very quickly...I lost one of my favorite breeder English Budgies one night from egg-binding, and even though I saw her suddenly become visibly sick and followed the exact protocol that I had used twice before with success, she just seized and died suddenly while I had her soaking in warm water in a steam filled room. It was awful to watch, and I was devastated, even though she was a breeder bird and not really a pet, not at all friendly or tame, and I had no interaction with her. It still was very traumatic.
Again I'm so sorry, this is in no way your fault, you got her vet care and did everything in your power to help her. This was just a sudden and unfortunately common occurrence with gravid females.
