If anyone is interested I’ve been able to pin down the problem, the problem appears when you launch the editor with a C++ class that contains a ConstructorHelpers::FObjectFinder call to a Blueprint-class that extends the C++ class itself. It can be circumvented by commenting out those lines, building the project, launching the editor, and uncommenting those lines, but it’s very tedious. Unfortunately in my project it would get a lot more convoluted without this code structure so I’m hoping for a fix for this sometime soon.
