This is caused by the loss of data in the ULScapeHeightfieldCollisionComponent::CollisionHeightData.
The CollisionHeightData is not marked as BULKDATA_PayloadInSeperateFile and is processed with a kind of lazy loading. (The data is temporary stored in AttachedAr pointer)
However, if GC runs between deserialization and actual use, AttachedAr will be lost with deletion of UPackage(LinkerLoad).
The following workaround can solve the error by loading data into CollisionHeightData in deserialization.
void ULandscapeHeightfieldCollisionComponent::Serialize(FArchive& Ar)
{
...
#if WITH_EDITORONLY_DATA
// For PIE, we won't need the source height data if we already have a shared reference to the heightfield
if (!(Ar.GetPortFlags() & PPF_DuplicateForPIE) || !HeightfieldGuid.IsValid() || GSharedMeshRefs.FindRef(HeightfieldGuid) == nullptr)
{
CollisionHeightData.Serialize(Ar, this);
DominantLayerData.Serialize(Ar, this);
CollisionHeightData.Lock(LOCK_READ_ONLY); // workaround
CollisionHeightData.Unlock(); // workaround
if (Ar.CustomVer(FFortniteMainBranchObjectVersion::GUID) >= FFortniteMainBranchObjectVersion::LandscapePhysicalMaterialRenderData)
{
PhysicalMaterialRenderData.Serialize(Ar, this);
}
}
#endif//WITH_EDITORONLY_DATA
}
}
}

Crash occurs. We can see an error log before crash
