The crash is due to a "Restless Draugr", possibly something related to its skeleton.
It is definitely not caused by my Master Occlusion Field, which just appears because it is one of the mods modifying the cell containing said draugr ("FolgunthurExterior01"). You can ignore all the other mods that appear alongside it, they are likely not the cause either
Edit: do know you have a ShadowSceneNode/WorldRoot Node mentioned in the log, which are notoriously very hard to debug... Those are often caused by lighting (facelight mods and the like cause this 100% sure) or camera related mods
