Hello, to those who are having this issue, including myself. The path to the assets most likely responsible for the issue are ghost assets, as in they don’t exist in the filepath dictated by the engine. Which is most likely why this issue is causing so much trouble to fix.
D:/Unreal Engine 5/UE_5.1/Engine/Content/ExternalActors/Maps/Templates/OpenWorld/0/IT/MHSUN7EJKDAAL8CVT31B9U.uasset
D:/Unreal Engine 5/UE_5.1/Engine/Content/ExternalActors/Maps/Templates/OpenWorld/0/CC/WDYA7H76HHF9UENRUYXBJA.uasset
So my guess is the issue lies somewhere within this problem, but I’m only theorizing. Please Epic Games, get this bug fixed. Its unbelievably annoying, particularly now since the above solution no longer works for 5.1
