I think this issue is mostly caused by users accidentally pasting a lot of text from (for example)a blueprint node while renaming a component. All you have to do is have a BP node in your clipboard and paste that into the name field of a component and you will get a crash. This can be triggered by any text as long as the amount of characters exceed 1024. Copying a blueprint node is just an easy way to do this.
USER PROVIDED INFO
RESULT
Engine crashes immediately.
EXPECTED
A large amount of text gets pasted into the name field. Or it gracefully rejects the name.
