Hey @Kolodinski0895,

Thanks for confirming the reproduction in the clean Samples project, that was really helpful!

This is a confirmed bug. It’s the same issue reported by another user in [this NDisplay thread](https://community.cesium.com/t/cesium-crashing-ue5-7-ndisplay/46284), where `GetPrimaryWorld()` can return null and the code dereferences it without checking. It was a regression introduced during a recent refactor.

Good news: the fix has already been merged ([PR #1844](https://github.com/CesiumGS/cesium-unreal/pull/1844), fixing [issue #1841](https://github.com/CesiumGS/cesium-unreal/issues/1841)). It’s slated for the **June 2026 release**.

In the meantime, you could remove all versions of the plugin you have (Engine and Project) and grab the latest from github yourself, or implement the same workaround locally while you wait for the release.

Thanks for reporting this, and sorry for the trouble!
