Hey, yesterday I updated to 5.2 and ever since that my smart object system seems to be broken, whenever i stop the simulation, the engine crashes, if i quit the packaged game the game freezes and crashes.
the following error “Assertion failed: OwnerController->GetPawn() [File:D:\build++UE5\Sync\Engine\Plugins\Runtime\GameplayBehaviorSmartObjects\Source\GameplayBehaviorSmartObjectsModule\Private\AI\AITask_UseGameplayBehaviorSmartObject.cpp] [Line: 271]”
it was working perfectly in 5.1
Some additional information, the crash only happens if the user exits the game / editor while the AI is performing the task, and the behaviour not ended yet
Exact same thing happens to me
Hey there, an user was able to provide an unoffical solution, it worked for me , altough for me i had to do the oppoite of what he said when it came to the build.cs file 
End simulation during “Use Claimed Gameplay Behavior Smart Object” Node crashes editor - Programming & Scripting / AI - Epic Developer Community Forums (unrealengine.com)
I applied this solution but it didn’t work. Is there any other solution for this problem?
