Anim Graph Missing From Child AnimBP (4-27)

I made one AnimBP a child of another. I was able to edit the graph fine, make new states, etc. I closed and re-opened my project and now I’m unable to open it as the option is completely gone. Anyone know how to get it back? This is infuriating. Pic 1 is the missing animgraph. Pic 2 is the parent.
