Spamming Ctrl + Y crashes the game in the editor

[G1TMACHINE]

This didn't really happen much previously but now it keeps crashing when i press it for 4 - 6 times consecutively.

Side note: The map I was working on also disappeared after I re-opened the game. I refreshed and it came back.

Unless you have a solid repro for this, it's unlikely we'll be able to provide a fix (stable is feature locked and tracking down rare issues like this is quite high effort).
