Summary
My dynamic assets being added stopped working with UE 5.8. The reason is the code change in UAssetManager::AddDynamicAsset.
5.7:
TypeData.FindOrAddAsset(PrimaryAssetId.PrimaryAssetName, FSoftObjectPtr(AssetPath), AssetPath, AssetPathMap);
if (BundleData.Bundles.Num() > 0)
{
CachedAssetBundles.Add(PrimaryAssetId, MakeShared<FAssetBundleData, ESPMode::ThreadSafe>(BundleData));
}
5.8:
if (BundleData.Bundles.Num() > 0)
{
TypeData.FindOrAddAsset(PrimaryAssetId.PrimaryAssetName, FSoftObjectPtr(AssetPath), AssetPath, AssetPathMap);
CachedAssetBundles.Add(PrimaryAssetId, MakeShared<FAssetBundleData, ESPMode::ThreadSafe>(BundleData));
}

Steps to Reproduce
Add a dynamic asset with an empty bundle data
FAssetBundleData GameDataBundles;
AssetManager.AddDynamicAsset(MyPrimaryAssetId, MyDataAssetSoftObject.ToSoftObjectPath(), GameDataBundles);
Now when you try to load this it will fail because the assets was never added because GameBundleData is empty. That used to be ok in older versions.
Expected Result
Asset should load using StreamableHandle = AssetManager.LoadPrimaryAsset(SkinPrimaryAssetId, Bundles, Delegate);
Observed Result
It fails to load the dynamic asset that was added because I did not associate it with a game bundle data.
