I added an widgetBp to view port,whick was call by Event begin play in actor, just like you guys did. It cuased a crash in AddtoViewport in UUserWidget. I checked the code in debug mode, The Problem came from code: Viewport = World->GetGameViewport(); Viewport is null, So it crashed in the next sentence.

Ah is the of running UMG code on a server?
