Loading multiple bundles using AssetBundle.LoadAssetAsync freezes editor

Asset Bundles


How to reproduce:
1. Open user's project
2. Enter play mode

There is a low chance that the bundles will be loaded successfully, in that case just reenter play mode and it will reproduce

Expected behaviour: Successful asynchronous asset bundle load
Actual behaviour: Editor has a high chance of freezing/locking up when loading the bundles

Reproduced on: 5.5.0f2, 5.5.0p2, 5.6.0b2
Not reproduced on: 5.4.3p4*, 5.5.0f1
Regression introduced in: 5.5.0f2

* - Crashes when exiting play mode after the second run

    I'm really surprised this is still broken.

    Is LoadAssetAsync not the primary mechanism we should be using to load things? The fact that this would be broken for any length of time makes me believe there's some other way Unity prefers us to do things.

    There's no way the critical path would be so fundamentally broken like this, right?

    Is the issue loading multiple assets from different asset bundles, or loading the asset bundles themselves?

    If I wait for one async asset bundle load to complete before kicking off an async load of another asset bundle, will I be ok?

    Still no update on this issue? I'm on 5.50f3 and Editor is still freezing

    Looks like it still happens in 5.5.0p4...

    Can we get any update on this issue?

    This makes 5.5 completely unusable for production: both editor and a game build hang up within seconds after loading any level (always multiple async assetbundle loads).

    your just change some asset property ..and build assetbundle..then load 2 assetbundle at sametime. the editor will freeze
