Editor Memory Increases over time and Editor Process not Ending

Over the last few weeks as I’ve used the Editor it has increased the memory usage dramatically over the course of 1-1.5 hours of a session to the point that I need to close and re-open the editor to fix and regain performance. When I go to close the Editor after that period of time the process in task manager does not end on it’s own. When the task is left in the task manager it increases between 50-100mb of memory per Task Manager update tick until I force end the task.
