I tried to make asset bundles from this scene and it works correctly. At least for me.
Here you need to test what is wrong on your side.
For example, I saw information that missing scripts can cause crashes.
Make a backup of the scene and try to isolate the problem as much as possible.

I'm using the UIBubble Popup for the POIs on the map. It works fine when building for both iOS and Android but When I try to build an assetbundle for iOS and/or Android with the Canvas and the tooltip in the scene hierarchy it crashes the unity immediately. I cannot add the assetbundle tag to the scene or even if I create a prefab from the GameObject <canvas> the assetbundle crashes the unity. If I delete the Canvas from the scene hierarchy it builds the bundle like a charm. Do you have any idea on what could be happening? I tried lots of changes in the code and the hierarchy and still crashing when building the assetbundle for iOS. iOS Unity version is 2018.1.0f2 and Android is 2018.2.15f1.

Attached you'll find a screenshot from the inspector.

Thanks for your help.
