If Tick Interval is set to something non-zero, the game will freeze when Set Game Paused is called. If not manually closed through the Task Manager, this will lead to an out of memory crash. This occurs across PIE, Standalone, and packaged games.
The editor is completely unresponsive and cannot exit PIE
Editor buttons can still be interacted with if viewport is paused.
