Crashing When I try to Re-Open Project (Blueprint w/ Custom Class & Animation Blueprint)

Call stack error: 9e2a8695b97e75b90d4067e977022f02

We have a sandbox project with some assets I migrated from the RTS demo project. We have a modified version of TopDownCharacter that our Blueprint (myDwarf) is using as a Custom Class.

I have tried adding some test nodes to the Animation Blueprint’s Event Graph (Dwarf_Anim_BP), in the style of the tutorial on using Anim Montage’s to cycle between punching animations while a button is being held down.

After a couple days of hair-pulling and many attempts of slowly rebuilding my assets in the editor, this error seems to start occurring once I try to casting to myDwarf. When this node is removed the crash/error goes away.

Strangely, this is the exact call stack error I was getting in a completely separate test project when trying to copy+paste one state machine inside of another:
