I’m guessing something like Long QT syndrome. My sisters have it and my older sister died from it. Many people who have it never have symptoms until they go into sudden cardiac arrest, which was the case with my sister. We didn’t know she had it until after she died. Anytime a seemingly healthy young person collapses like this, I have to wonder.

I'm so sorry for your loss. Grief is ridiculously challenging, and I can only imagine how much harder when it's completely unexpected like that.
