The attached project crashes whenever one of the structs is being opened.
This does not occur in 4.10.4, this is a regression.
Found in 4.11 Binary, reproduced in Main CL 2930737.
User information: "The interesting thing about that is if I delete the structs I've made, I can open the Blueprints. If I now build new structs (with new names, the old ones are still used) and change all blueprints I can get it running like in 4.10. but after a restart of the engine everything crashes again as if I've changed nothing."
1. Migrate the content located here into a new project: [Link Removed]
2. Navigate to Blueprints->Dialogue System
3. Attempt to open the DialogueStructEvent Struct
Result: Editor freezes briefly and then a crash occurs.
Expected: Struct would open without issue
Fatal error: [Link Removed] [Line: 131]
