"Cancelling DisplayDialog.." error is being thrown when entering the play mode after AssetBundle.Unload(false)

Asset Bundles



Priority: 7Not yet prioritized for a release


Severity: 3Workaround is possible

To reproduce:
1. Open user's attached project
2. Switch platform to iOS or PC
3. In the menu bar press Project -> AssetBundle
4. Enter play mode and inspect the console

Note: If you can't reproduce the error try reproducing it few times.

Expected result: No errors should be thrown, asset bundle is loaded successfully
Actual result: "Cancelling DisplayDialog because it was run from a thread that is not the main thread: Opening file failed"
^ error is being thrown

Reproduced with: Unity 2017.1.3p2, 2017.2.1p4, 2017.3.1p3, 2018.1.0b11, 2018.2.0a4

Note: Reproduced with iOS and PC platforms but wasn't able to reproduce with Android platform. Also, commenting AssetBundle.Unload(false) in App.cs seems to fix the issue.
