Hi @958627869,

Thanks for your report, and for including the error logs!

First, it would be helpful to know how you installed the plugin. Did you install it through the Unreal Marketplace? Or did you download it from Github? It may be worth a try to build the plugin locally.

Second, I noticed that you are using an older version of Unreal Engine and Cesium for Unreal. It would be helpful if you could upgrade your project version to check whether the latest version of the plugin has this issue (v2.7.0). If you’re worried about upgrading, you can always make a backup copy of your project.

Let us know what happens!

Yes, I installed the cesium plugin through the Unreal Market. Due to severe memory leakage issues with higher versions of UE, I am unable to upgrade UE. Alternatively, you can try creating a simple project that includes pixel stream plugins and cesium plugins, and try packaging it to see if it reports any errors
