Deadlock when loading textures with UnityEngine.AssetBundle.LoadAsset() on M1 iPad Pro

[j_maruhashi]

Using UnityEngine.AssetBundle.LoadAsset() to load the textures contained in an AssetBundle will rarely cause a deadlock within this function when run on the M1 iPad Pro.

The callstack when a deadlock occurs is as follows.

The version of Unity used for the build is 2020.3.20f1.

As a symptom

Unity 2020.3.20

Graphics: Fixed a race condition deadlock when loading textures synchronously. (1353805)
Seems to be similar to.

I am in trouble because I do not know how to deal with it, so if you have information, please provide it.

I found a similar deadlock on Windows (Editor), Windows (Player), and Android.
