Hi @Ej1423 ! Thanks for reporting this problem. Can you explain a bit more what you mean by "adding a block"? A few detailed steps of what you were doing would help greatly find where this problem comes from 👍

Quick analysis from the component stack. It looks like this is coming from the component ItemRow used in SortableVirtualizedItemList A hypothesis is that the problem comes from the ObjectsList or the ObjectsGroupList. I found that a .find() method is used in both:

https://github.com/4ian/GDevelop/blob/aed4b76a3f87f8b090792b14ce87b7a2b693fbe3/newIDE/app/src/ObjectsList/index.js#L639-L641

https://github.com/4ian/GDevelop/blob/aed4b76a3f87f8b090792b14ce87b7a2b693fbe3/newIDE/app/src/ObjectGroupsList/index.js#L392-L396

But not sure if this could be coming from here, as I don't see how those elements could be undefined.
