When adding the Add Component By Class node, choosing a class that has a Relative Transform pin, changing the transform, and deleting the node the editor crashes. I tested this with the Skeletal Mesh Component and Arrow Component classes. Adding another class like an Actor Component that doesn't have a Relative Transform pin and then deleting it does not crash the editor.
Additionally, the editor only crashes after changing the Relative Transform pin. If you delete it beforehand there is no crash. I also tested the Add Skeletal Mesh Component node by changing the relative transform and then deleting the node and no crash occurred.
The node does not exist in 4.25, so not marking as a Regression.
**The editor crashes
The user can delete the node without error
