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

    Looks like 5.5.1p1 claims to have the fix for this. Trying it now...

    Is there somewhere we can see when 5.5.2 is coming out?

    Asset bundles are pretty much broken with any new feature, it's been like that since the release of the 5.x branch. At this point, I'm just use to it...

    The only thing that changed for us is that editor & a build no longer crash, but they just freeze forever, 0% CPU use.
    Definately not fixed.

    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?
