To reproduce:
1. Open attached project
2. Go to Tools> Build Window
3. Click on "Build Asset Bundle and Play"
4. Press "A" on the keyboard

Actual result: Unity editor crashes
Expected result: Unity editor does not crash

Not reproducible: 2017.4.20f2
Can't check on 2018.2 due to package C:/Users/martyna/AppData/Local/Unity/cache/packages/,43): error CS1061: Type `UnityEditor.PackageManager.PackageInfo' does not contain a definition for `author' and no extension method `author' of type `UnityEditor.PackageManager.PackageInfo' could be found. Are you missing an assembly reference?

From 2018.3.0a1 till 2018.3.0b1 everything is irresponsive. ( In the play mode nothing happens when you press "A". Normally if you would press D or B it will show in console debug log doesn't crash. In this case, there is nothing.

    I submitted a bug which has been identified as a duplicate of this one.

    The issue for me happens only when unloading a bundle with Unload(True)

    Before, I would unload bundles then destroy all the objects in the scene.

    Now I have to destroy the objects first and wait one frame (to make sure the object has been destroyed) and then Unloading the bundle works fine.

    If I don't wait for one frame it will throw a lot of errors and ultimately tell me Unload has failed.

    If I don't destroy the object prior to unloading it will just crash.
