Crash on load new assets from mod folder

[codeard]

Is it possible to load new assets such as models or materials, or do assets have to be previously registered in the engine build?
When add new assets in blueprint game will crash on stratup with acess violation, even if they has to be used later.
Tried remove logic from BP and load with AssetRegistryHelpers:GetAsset(AssetData) from Lua script at runtime and got same crash exactly at this function, LoadAsset(path) return nil.
The biggest success is the texture on the 32x32 widget, but with a different size I get a serialization error

I wonder how material can be loaded from mod folder there

Are you calling LoadAsset in the game thread ? That's a requirement for this function.

The asset itself must also be structured correctly in the UE editor before packaging, and then it needs to be placed in the correct location in the game directory.
I don't have the expertise to help with that unfortunately, but maybe someone else can help you.
