Unreal Engine Issues and Bug Tracker (UE-94179)

Description
UObjects returned from "Get Item Children" in a TreeView widget causes an engine crash, due to invalid pointers.
User has proposed the following fix: The best fix is probably such: When Slate list views and tree views have UObject-based items, they should correctly tell the GC that they have references to those UObjects so they aren't freed. This would be the least surprising behavior for developers.
Alternatively, you could go with an option that causes the list view / tree view entries to revert back to nullptr when the GC frees them, if the intent is that the tree view or list view should not be keeping objects alive.
Steps to Reproduce
Project Sample included for repro:
Download & Unzip Project.
Launch UProject.
After loading the project in the editor, hit ~ and run gc.CollectGarbageEveryFrame 1 to get reliable reproduction.
Click Play in the editor and scroll the tree view.
Result: Engine crash, due to "use after free" of UObject pointers.
Expected:
No Engine Crash.
