What Happened
I discovered this purely by accident, but it should highlight some new functionality that needs to be added.
If there's a script on a node, you can still add a BlockCode to it. I assume that is not behavior that should happen, especially since it causes problems.

If I had to pick a fix for it, I'd say if you to attach a BlockCode to a node that has a script already, you should get a popup saying "You can't add a BlockCode to a node with an existing script!" (and also not let you add it of course).
How to Reproduce
- Add any node to a scene
- Add a script such as the starter player script
- Add a block to the same node
