Hi. I found app freezing issue related to Resources.Load() and AssetBundles. If you calling Resources.Load() while asynchronously loading other assets from AssetBundle by using UnityWebRequest, main thread is freezed. This only occurred on Android/iOS device, not Editor. And reproduced by both Unity 2020.2.0b2 and 2020.1.5f1. Minimal reproducible project was sent as Case 1277297.
