Hi! Ive been using UE for about 2 years and recently Ive been encountering a problem where at random times, the engine starts rhythmically hitching as shown in the video attached. I also attached what I could get from the live insights feature. its driving me mad and I cant seem to find out whats doing it as it just appeared out of nowhere. I cant continue on my project with this issue and i would appreciate it so much if someone could help me out 
Based on the insights its something to do with rendering perhaps, or something with “waitingfortasks”. Its weird because its on a basically empty map, and it happens on all levels regardless of whats in the level or not.
Thank you in advance
