Was working on my mod then I hit play and a similar error popped up to the one below. Now anytime I try to open the dev kit I get the following error. Not sure what to do.

Assertion failed: !HasAnyFlags(RF_NeedLoad|RF_NeedPostLoad) [File:C:\SVN_Ark\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectLinker.cpp] [Line: 96]
Detaching from existing linker for …/…/…/Projects/ShooterGame/Content/Maps/TestMap.umap while object SceneComponent /Game/Maps/TestMap.TestMap:PersistentLevel.Structure_Canopy_Stall_C_1.SceneRoot needs loaded

Have you tried to Verify your ADK? At the Epic Games Launcher> ARK (Dev Kit)> Launch theres an arrow just to the right of LAUNCH, click on that and there are two options: Uninstall and Verify. Verify may fix any “accidents” that happen to the Core Ark files.

I had issues getting my dev kit to start if i installed it from steam>library>tools. But by using the epic games launcher to download and run itI was able to start it without issues
