I grabbed the example projects from here and opened up the Scene Loading project: https://github.com/Unity-Technologies/Addressables-Sample It works fine in the editor, but when I do a PC build it fails. I've tried various things but it all ends up the same. The Bootstrap scene loads as expected, but when I click the button to Transition to the Next Scene it doesn't seem to fully load the scene. I'm using Unity 2018.4.10 with the Addressables Package 1.2.4 (and also tried Addressables 1.1.5). Please see the attached screenshot and output log for more info.
