Set Mouse Cursor Widget back to Default

Hey there fellow developers,

I have a quick question. How do I revert my mouse widget back to none or simply the default cursor?
I’m currently using this node (See picture).

And that one works fine. However when I want to reset the cursor back to the default cursor and I use the Cursor Widget with none Unreal just completely crashes.
What is the proper way to go about this?
