UE4 taking a long to leave ram after closing

Hi All

UE4 not leaving memory even after closing for 4 mins. it is showing less memory in one tab, but the last image, you can see where it left, and in task manager, you can see most of my memory is used at the bottom.

You even find a solution for this? I’m running on a potato, but even still I feel like UE4 shouldn’t take 15 minutes to finish closing
