DataAsset broken???

I am using UPrimaryDataAsset, i can make a BP of it in editor, and from this BP i can make a DataAsset. However, when i close the engine and re open it, it looks like on the left side of the image and I can´t use it as a variable anymore. But if I open the BP, the DataAsset turns red and suddenly i can use it. Only when closing the editor and re opening it, everything breaks.
Also, i sometimes get Errors in AssetContextMenu.cpp, where everything turns red. I tried updating all my stuff from visual studio to UE5

You need to add this Primary Data Asset in the Asset Manager in Project Settings, for instance like that:
