Null reference error when running the EPiServer Find Content Indexing Job scheduled job
Hey Benjamin,
Can you try running this job "Remove Unrelated Content Assets" and after that try to reindex.
Let me know if it works.

Have you checked the logs because its seems like some property is empty/null or pointing to page/block that is not exist anymore.
