Editor Launch Crash "Unknown structure."

Each time I try to launch I get an error around 93%, I don’t know what would cause this, I deleted some presumably irrelevant blueprint, and the editor crashed. What’s baffling me is that that blueprint is not mentioned in the error report. I’ve hardly touched anything as of late that would result in “PARENT_BP_Item_Coin.PARENT_BP_Item_Coin_C:ItemInfo” being mentioned. The blueprint doesn’t even appear deleted, it’s still in my content folder.

The error is as follows:

[ 0]LogProperty: Error: UStructProperty::Serialize Loading: Property ‘StructProperty /Game/Blueprints/CoinType/PARENT_BP_Item_Coin.PARENT_BP_Item_Coin_C:UserConstructionScript.K2Node_MakeStruct_F_SpecificItem’. Unknown structure.

I’ve also done this: - which has not worked for me. I’m very confused, as this error suggest that the editor is operational.

I’ve also seen it said to “fix up redirectors”, I don’t know how to do this outside of the editor.

I’m a little dismayed here, I’m close to getting this project on the market and I have this happen. Any feedback would be greatly appreciated.

I’ve managed to get a response from the editor by creating a new project and transferring the contents there, I can manage “PARENT_BP_Item_Coin” and its children, datatables, enums, structs… But, if I try to open any other blueprint, be that the game-mode, my character blueprint, any widget, it crashes.

I’m guessing there’s an inconsistency concerning a variable related to a struct, but I can’t get to it.

The Generate Visual Studio Project option is not available to me.

Problem solved by moving my character bp into another folder, this broke everything but allowed me access to fix whatever disconnects.
