Can you give us more information about what caused the crash? For example,

What objects were in your scene?
Did this crash happen in the Editor or at runtime?
What did you do leading up to the crash?

I have the same problem, there no special things in the scene, i have some BP class and ocean plugin, make some even trigger in the sequncer, and i first crash out when i want to simulate in the viewport, but no problem ever before, it doesn’t work after it crashes once.

When i turn off ndisplay plugin, i even cant go into my project

I guess it was caused by a plugin called “DasMqttPlugin” in the Unreal Mall

In the editor

I collapsed without doing anything

_RU · April 11, 2023, 4:59am

Did you fix that? I cant find the DasMqttPlugin

_RU · April 11, 2023, 5:03am

I open the cesium samples project and it look no problem! So confusing！

_RU · April 11, 2023, 6:34am

What’s going on?

I bought this plugin from the Unreal Mall, it’s too bad and it keeps crashing
After I switched to another plugin ,
Ue5.1 will no longer crash and
Cesium will no longer report this error

If you can give us examples, i.e. simple reproducible scenes where the crash happens in Cesium for Unreal, we can try to troubleshoot. Otherwise, it seems like the crashes are due to interactions with other plugins, and I’m not sure how we much we can help.
