Hello everyone,
Yesterfay everything was working fine, today morning, when I launch the engine it crashes with following log:
Assertion failed: Existing.Linker->ExportMap[Existing.LinkerIndex].Object==this [File:D:\Build++UE4\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectLinker.cpp] [Line: 107]
What is going on?

I’ve gotten the same issue twice now. I found that there were three UIs which made this happen to me. Compiling any of them or trying to open a level which BP was referencing them crashed the engine.
I removed the three UIs and re-made them. The issue went away. But today I closed my project and tried opening it again, and the same issue appeared.
Those UIs were not complex in any way. Background image and a few buttons.
