Hi, I have exactly the same problem.
I have just finalized my hud widget (display health), then in the level blueprint I use the “create widget” node to create my interface and display it with the “add to viewport” node. In the editor all works fine. But when I test it with a dedicated server, I have some error in the server log (can’t find the Script/UMGEditor …) and then the server just crash.
I have made a new test with the First Person Template. Same issues occurs. Addind a widget in the project, create it with the “create widget” node and the crash arrive on a dedicated server.
Any solution ?
