Android crashes with Unity 2019.4.40f1


We have our game on Google Play for a while. Our latest version was built using Unity 2019.4.34f1 and everything worked just fine (almost no crashes).

Recently we updated to 2019.4.40f1 and with some changes to Monetization released new Version. After that, crahes skyrocketed. After decoding with symbols we got this stacktrace

No need to say that we made no changes to instantiation, prefabs or workflow. It originates from our pool controller and on top there are lines indicating that the problem is from animator.

We managed to fix the problem. It was caused by a prefab that was in scene, but in another AssetBundle. It happened when player went from this scene to a new one a then we tried to instantiate the asset from the bundle.
