Has this workflow ever run before successfully and suddenly started failing? Is this cloud or onprem? Happens in local or higher environments?Is it a custom workflow? Please add more context. Add the whole stacktrace in attachment to review. There maybe permission / repository errors blocking. Now rename asset is indeed expensive operation. One recommended way is to use Assets API. Adobe has already deprecated AssetManager API.  If this is custom workflow, running java assetmanager api, not surprised if it fails. You should move to Assets API.
