[BUG] Building Asset Bundles never finish building (Write Serialized Files)

I'm currently trying to build simple asset bundles via the addressable system in Packed Mode.
I've tried almost every setting there is, with almost all variations, but it just won't finish building my asset bundles.

Here is the state in which Unity gets stuck at the step "Write Serialized Files".

I'm just wanna pack one of our scenes into a bundle. It does work with a simple or empty scene and it does apparently work if I delete ALL of the models in the scene, but that is obviously not what I wanna do here.

Hope anybody has encountered this problem before.

Unity Version: 2018.2.18f1 (same Problem in 2018.2.13f1)
Addressables Version: 0.4.8

EDIT: Seems like the Lighting settings of the scene I was loading were just too extreme.

 

I have the same issue, the lightmaps seems to be the problem like you mentioned. Have you found any solution or workaround?
