when I modify the code as follows, the crash is gone。

It seems that the string from the asset_child is collected by GC when passing to the dictionary as a parameter.

        while (iter.MoveNext()) {
            var bundle = iter.Current.Value;
            var ab = bundle.assetBundle;
            var asset_child = ab.GetAllAssetNames();
            var scene_child = ab.GetAllScenePaths();
            for (int j = 0; j < asset_child.Length; j++) {
 -                var s = (string)asset_child[j];
+                var s = (string)asset_child[j].Clone();
                var a = new Asset(bundle, s);
                name_to_asset[s] = a;
            }
            for (int j = 0; j < scene_child.Length; j++) {
 -                var s = (string)asset_child[j];
+                var s = (string)asset_child[j].Clone();
                name_to_asset[s] = a;
            }
            bundle.unload(true);
        }

Bit outside of my skillset, but could you check memory usage? Maybe the first code causes a memory leak?
If memory usage for both is fine I suggest filing a bug report with the original code (so if it’s an actual Unity issue they can fix it) and use the new working one for production.

I profile the memory usage of the process via Android Studio, the process only used 380MByte.

If that’s the usage when it crashes maybe open a bug report yeah
