I’m using Unreal Engine 5.1.0, and every time it autosaves out of date packages, the editor crashes. This also happens in brand new projects, and I can’t fix it no matter what I try. Here’s my error log:

```auto
Fatal error: [File:D:\build\++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectGlobals.cpp] [Line: 332] Illegal call to StaticFindObjectFast() while serializing object data or garbage collecting!
